The
Fascination of Aquariums
Take a dive with us ... Into the fascinating underwater world of aquariums. Every aquarium, be it small or large, has its own special charm. A fantastic wealth of colors and shapes, an exciting variety of forms of life and different behaviors. This modern form of the art of aquariums was made possible by Ulrich Baensch, doctor of natural sciences, the founder of TetraWerke and pioneer of the first industrially manufactured food for ornamental fish. He succeeded in developing a natural, nourishing and wholesome dry food appreciated by fish. TetraMin marked the decisive breakthrough of aquariums as a favorite hobby. For more than 50 years now Tetra is the hallmark of absolute competence and experience in every aspect relating to aquariums. Today we would like to tap our experience to stand by your side actively with useful tips and tricks. You can find further suggestions at our website www.tetra.net. So have fun with this brochure.

The most widespread type of tropical freshwater aquarium is especially recommended for beginners. Various types of plants and different fish species are kept together in the same aquarium. This means that they must not only adapt their social behavior to one another, but also the requirements in terms of the water quality, water temperature and aquarium set-up must be the same. Single-Species Aquarium Just one species is kept. They are often fish with special requirements, which need to be

Breeding Aquarium Mostly for specialists only. These aquariums are often not very appealing and have specific, partially extreme water values, as their only purpose is that of breeding fish. Tetra AquaArt Aquariums Tetra AquaArt Complete Aquarium Sets for the fascination of the underwater world. Not only do all AquaArt aquariums have a modern design in the trendy colour of silver – they are also equipped with innovative EasyCrystal® filter technology for crystal clear water and simple maintenance. Large, user-friendly openings make it even easier to feed the fish and gain access to the equipment. AquaArt aquariums are available in three sizes: Tetra AquaArt 20L Discover Line, Tetra AquaArt 30L Discover Line and Tetra AquaArt 60L Discover Line. Once you have chosen an aquarium species, you must consider the tank size, the position and the equipment. und die Einrichtung machen.
A good position is a room corner without direct sunlight.
Important: sockets near the aquarium!
Dark places are more suitable for aquariums - and they even have a more impressive effect.
Make sure that the carrying capacity of the bottom and the floor cabinet is adequate enough.
Once an aquarium is set up and filled, it can no longer be moved - therefore, planning is absolutely necessary when choosing the position. If possible, an aquarium should not be placed near a door, because any bustling may frighten the animals.
Choosing the Position To make fish feel themselves at home in your aquarium, a number of factors need to be borne in mind when choosing the position: you need a flat, shockproof, sturdy and level position with sockets nearby. Never expose an aquarium to direct sunlight. Sunlight can trigger an undesired proliferation of algae and lead to the heating of the water. Consider also the weight: besides the empty weight of the tank there is the equipment plus one kilogram of weight for each liter of water. Even a relatively small 80-liter tank can weigh quite a lot and

can no longer be moved once it is filled. Therefore the floor cabinet must be able to bear the relevant weight. Your local dealer has tanks of all sizes and all types of equipment. A good tip is to place a panel of Styrofoam between the floor cabinet and the aquarium to prevent point loads and to level any unevenness.

Setting up an aquarium There is always a plan behind any construction! How to become an aquarium designer - in this chapter you will find all of the necessary information on the substrate, equipment, plants, water and, of course, on how to set up your own aquarium. Important: The main focus of your thoughts should never be on the appearance of the aquarium but on the well-being of your fish.
TetraAqua AquaSafe, TetraAqua NitrateMinus Pearls and TetraPlant CompleteSubstrate by Tetra are the basic equipment for any aquarium owner.

Substrate Once you have washed the tank with water and then placed it in the position chosen, it must be filled first of all with the substrate. On the one hand, it offers support for the plant roots and, on the other, it serves as the habitat
for the microorganisms that are essential for an optimal biological balance. Gravel with a grain size of 1 - 3 mm or 3 - 6 mm will do well for social aquariums. Before filling the aquarium with the gravel, it must be washed thoroughly. But it is almost barren and it offers no nutrients to the plant roots. For this purpose Tetra offers a special substrate activator: TetraPlant CompleteSubstrate. This readyto-use concentrated substrate contains precious minerals, oligo-elements like iron, important micro-nutrients and natural black peat with a high content of humic material. It favors the growth of plants and provides for an adequate long-term nourishment. To avoid the proliferation of algae afterwards, there is TetraAqua NitrateMinus Pearls: all you

of your fish. Roots and stones must always be cleaned and, if necessary, boiled. Use only types of stones that do not release any substances into water. Minerals and stones containing metals are not suitable. Make sure that any technical devices have the space they need, as these need to be installed before designing your underwater world.
Decoration Create a real underwater world for your fish! For instance, you can use stones or roots from you local pet shop. Use decorations sparingly so that the fish can have enough space for swimming.

Heating Tropical aquarium fish require tropical water temperatures mainly between 24 – 27 °C. Every tropical freshwater aquarium has its own type of heating. We recommend Tetratec HT heaters. They are what we call rod heaters. They are small and discreet, but also extremely performing and safe. Filter To have an aquarium that works in the long run, you need a permanent filter. The filter collects clouding floating particles and keeps the water clear. But its other function is more important: thanks to the filter bacteria residing in the filter substrate, the noxious excretions released by fish are decomposed biologically into harmless compounds. An especially reliable solution is Tetratec IN Inner Filter plus. It is highly performing and easy to use and it is fit for aquariums of up to 200 liters. Besides the stepless regulation of the flow-through speed, the output nozzle can be turned by 180° and the incorporated Venturi system provides for an extra supply of oxygen. Alternatively, you can even use the air-operated
Brillant Styrofoam filter by Tetra. It is operated by an air pump (e.g. Tetratec APS). It drives the water with the aid of air through the filter sponge in which it undergoes an intense biological scouring. It has an excellent filtering effect in particular in spawning tanks and aquariums with scarce water currents. Tetratec EasyCrystal Filters are a real alternative to conventional aquarium filters. With their intensive physical, biological and chemical filtration, the filters ensure crystal clear, healthy water. Cleaning EasyCrystal Filters is a very easy process: simply change the filter cartridge every four weeks. No need to rinse the filter medium, no more wet hands! Tetratec EasyCrystal Filters are available in two different sizes: Tetratec EasyCrystal Filter 250 for smaller aquariums of up to 40 litres and Tetratec EasyCrystal FilterBox 300 with a heater compartment for aquariums of between 40 and 60 litres. If you prefer to use an external filter, or if you have a very large aquarium, we recommend Tetratec EX External Filters, which are available in three different sizes for aquariums of between 60 and 500 litres. Not only are they powerful and quiet to run, they are also easy to clean. Their integrated automatic starting function is particularly advantageous. This renders the intake of water during initial installation or after each clean unnecessary. There are five different filter media, which filter the aquarium both mechanically and biologically.
Lighting The artificial lighting of the aquarium is essential. The light determines, for instance, how plants grow. If the wrong light source is used or if it is too weak, the plants do not grow enough. Even algae problems can be caused by incorrect lighting. Plants require 10 to 12 hours of light every day. For instance, pure-white daylight tubes are recommended in particular.
Plants Aquatic plants have an extremely decorative effect on observers. But aquatic plants are important for the aquarium habitat for completely different reasons. They produce oxygen during the day and favor the elimination of contaminants that may be found, for instance, in fish excrements. Aquatic plants serve also as the spawning ground for some fish, create hiding places and act as natural territorial limits. Background plants All highly vegetative species such as many stemmed plants are suitable for the background. They often grow quickly yet scarcely in width. Medium range plants Lush solitary plants make a nice view for the observer and do well as catchy mounting points. Foreground plants Decorative foreground plants should remain quite small to avoid obstructing the view in the aquarium.
Floating plants Plants floating on the water surface offer fish hiding places and spawning places. They should be thinned out regularly, as they may otherwise deprive the underwater plants of too much light. Fast-growing plants should be used already during the first set-up so that the aquarium environment can be stabilized faster and better. To make the plants grow with a lush green color, we recommend the regular addition of TetraPlant PlantaMin. This liquid iron-intensive fertilizer assures lively, lush green colors.
The Tetratec Brillant Filter is especially quiet and performing and it is ideal for aquariums of up to 100 liters.
Water Water is the vital element of fish. Therefore, optimal water conditions are important both for livability and for a nutrition appropriate for the species. There are many additives in drinking water, e.g. chlorine, which make it hygienically clean. But chlorine is dangerous for fish even in low concentrations. Even heavy metals which are poisonous for fish that breathe through gills often finish in tap water. Tap water must be treated to make it appropriate for fish. This can be done safely and reliably with TetraAqua AquaSafe. This water treatment agent lastingly binds heavy metals and eliminates chlorine. The organic colloids it contains protects the delicate mucous membrane of fish.

Plants
Before placing the plants, make sure to shorten the roots and remove any damaged leaves. Then press the roots with caution into the substrate up to the root collar. Now you can finish filling the aquarium and start up the equipment. Fertilize your aquatic plants with TetraPlant Crypto Fertilizer and TetraPlant PlantaMin for lively and lush green plants.
5 Biological maturation process Before adding the fish to your aquarium, you must leave it to “Rest” for two weeks. During this period the aquarium becomes “biologically active”. The filter bacteria start to settle in and proliferate. Without an adequate number of these microorganisms it is impossible to achieve a biological balance appropriate for fish and plant life. Use TetraAqua SafeStart to add your fish in aquarium immediately. SafeStart provides for immediate biological activity of your aquarium

Plants, fish, water and light form, together with the decorative elements, a harmonious and exciting view. The aquarium system can work perfectly only if the technical equipment, water, fish and plants are adapted one to the other. Water plays an especially important role. The quality of the water as the vital element of fish is decisive for their health and well-being. But even the thriving of plants and microorganisms depends directly on the water quality. The monitoring of important water values and the regular partial changing of the water are extremely important for a truly professional aquarium. By changing the water regular about 20 to 30 % of it is replaced every two weeks with fresh water. Thanks to TetraAqua AquaSafe you can make tap water immediately suitable for fish and natural, neutralize any hazardous substances and add colloids with a protective function on the fish mucous membrane. The BioExtract formula also favors the development of useful filtering bacteria and provides healthy, clear water. Instead of frequent water changing, thanks to TetraAqua EasyBalance, you can maintain a fish and plant-friendly balance of all of the essential water values and hence reduce the number of times you need to
change the water. EasyBalance gives your fish the important vital substances they need, stabilizes effectively the pH and CH value of the water and reduces the concentration of phosphate and nitrate. Its regular use keeps the aquarium water biologically healthy for up to 6 months. Important: AquaSafe should be added every time you add tap water to assure the long-term maintenance of your aquarium. Any aquarium owner wants to and should provide the best living conditions for his fish. Besides using AquaSafe, it is necessary to know the quality characteristics of the original waters where tropical ornamental fish live. Tropical freshwater fish from the “blackwater� regions can be taken care of appropriately as each species requires by adding TetraAqua Blackwater. It transforms aquarium water into brownish-crystal clear tropical water also known as blackwater. In addition, you can prepare your aquarium water regularly with TetraAqua TetraVital. Tap water often lacks important oligo-elements like iodine and vitamins that fish absolutely need during particular moments of their life like the spawning season. TetraVital favors their overall well-being and improves their resistance. The vitamin B complex also favors the growth of plants and microorganisms.
The thriving of fish and plants requires appropriate environmental conditions in the aquarium.
Is the chemistry right? Only if the water quality is right will your fish feel good. You should know the following water values: Total hardness (TH) The TH value is determined basically by the content of calcium and magnesium. If their content is high the water is hard, while if it is low it is soft. The total hardness influences significantly the organic functions of all forms of aquatic life and it is measured in °dH = degrees German hardness.
Carbonate hardness (CH) Almost every type of water contains hydrogen carbonate whose content in water is indicated by the CH value. Hydrogen carbonates play an important role in the aquarium because they act as a pH buffer and hence prevent an excessively sharp and sudden alteration of the pH value owing for instance to a drop in acidity. The CH value has a direct influence on the well-being of fish. In freshwater aquariums the CH value should not amount to less than 3°dH.
Only if the water values are correct will the fish feel good.
13
All Tetratest products are available in pet shops either singularly or in sets.
Acidity (pH value) The pH value of the water is the result of all of the acid and basic substances dissolved in the water. These substances can make the water either acid or alkaline. If the pH value is 7.0, the water is neutral. The more acids are present in the water, the lower the pH value drops; the more alkalines are present, the more it rises. It is recommended to measure the pH value of your aquarium once a week. The pH value depends directly on the carbonate hardness and on the carbon dioxide content (CO2). If the carbonate hardness or CO2 content changes, the pH value changes automatically as well. This is the principle at the base of TetraAqua pH/KH Minus and pH/KH Plus, which can help you to adjust easily the pH value and the carbonate hardness of the aquarium water. Ammonia, Nitrite, Nitrate The excrements of fish as well as the remains of plants and food release nitrogen compounds into the water of any aquarium and these compounds need to be broken down in various steps. First comes toxic ammonia or

non-toxic ammonium. It depends on the pH value. At pH values of more than 7.0 there is a prevalence of ammonia, while at lower pH values non-toxic ammonium is formed. In the case of sensitive fish even a low content of ammonia in the water can have damaging effects in the long run. The filter bacteria of the Nitrosomonas genus break down ammonia or ammonium into nitrite. But nitrite is extremely poisonous and it can be extremely harmful in the long run or even deadly. It is broken down by the filter bacteria of the Nitrobacter genus into nitrate. Nitrate is a plant nutrient which favors however the growth of algae. Just one application of TetraAqua NitrateMinus can reduce lastingly the nitrate content. Ammonia and nitrite are harmful already in low Tetra Information Here are some tips to avoid straining water: - Avoid too many fish and plants. - Add food several times a day and just as much as necessary for the fish to eat in a few minutes. - Make sure that the aquarium is adequately filtered and aerated. - Regular partial changes of the water or use of TetraAqua EasyBalance are important maintenance measures. - Clean the bottom regularly. - Healthy plant growth is extremely important for an aquarium that works properly.

Organic wastes
Organic wastes are, among other things, a part of what is called the nitrogen cycle. Compounds containing nitrogen found in fish excrements and in plant remains are transformed by filter bacteria (e.g. TetraAqua SafeStart) into nitrate during various stages. Plants absorb the nitrate as a nutrient. TetraAqua NitrateMinus, in liquid form, helps keep the nitrate content at a constantly low level when applied weekly. Even by using TetraMin Crisps less nitrate ends up in the aquarium water.

concentrations (at least in the long term). If you detect ammonia and nitrite with Tetratests, it means that the biological filter is not working properly and that the situation is already or could be dangerous for your fish. Possible countermeasures for aquariums already with fish include: frequent partial water changes, less food and fish, checking of the oxygen supply.
the optimal biological balance and that the aquarium system is not working properly. Water tests give sure results and help you to identify early on any disturbance and prevent damage. By comparing with a color scale or with the number of drops that it takes to change the color, you can determine precisely the current water conditions. Tetra Water Tests come singularly, as refill packs or in sets.

Choosing fish
Adding your fish
In a social aquarium the needs of the fish in terms of water quality, temperature and light must be more or less the same. But this does not mean that your aquarium will be boring: when buying your fish, choose them from different swimming areas. For instance, the Marbled Hatchetfish swims mostly near the water surface,
When you buy fish, they are put into a special bag. Make sure that the fish is not left too long in this container. The longer the way home is, the more air or oxygen should be available in the bag. Adding your fish is a delicate operation which must be handled with great caution. To avoid stressing or, in the worst of cases, harming your fish owing to sudden and drastic changes, you should put the closed bag for about twenty minutes in the aquarium. In the meantime the difference in temperature is stabilized. Then open the bag and add water little by little water from the aquarium so that the other water values are gradually stabilized. Important: Never add fish without this acclimatization phase! This is the only way to avoid the shock resulting from the change of environment. This way your fish should be able to feel themselves at home right from the beginning.
Neon in the mid-water regions, while almost all catfish stay near the bottom. By “populating” all of these areas, you will not only enliven your whole aquarium, but you will also avoid that too many fish swimming “fin by fin” in the same water region. Less is often more. Even if it is difficult, try to avoid too many different fish species. A few, well-chosen species are more interesting than a big variety. Beginners, in particular, should start with just a few fish species. A general rule of thumb for the right relation between the aquarium size and fish density is the following: to make sure that your fish can live peacefully, they should have at least 1 - 2 liters of water per centimeter of length.

This is what to do: 1. Temperature stabilization in the closed bag - the greater the difference, the longer you should wait. 2. - 4. Slow adaptation and acclimatization to the water in the aquarium by adding water gradually. Avoid absolutely sudden and drastic changes. 5. Free the fish from the bag into aquarium.

Favorite fish species Fish are what make an aquarium a truly vital place. There are numerous species that you can keep at home - here is an overview of the most common and favorite species: 1 Sunset Gourami They belong to the labyrinth fish. This colorful species prefers the company of smaller and calmer fish and it adapts best to well illuminated, densely vegetated tanks with a dark bottom. For reproduction make a tall, fixed foam nest. The male takes care of the brood.
18
2 Bolivian Ram The Bolivian Ram belongs to the cichlids family. Not only their beautiful colors but also their interesting social and reproduction behavior make cichlids a long-established favorite aquarium fosterling. It is a peaceful species that can get rowdy at times. It is recommended for single-species aquariums; otherwise it should kept only with calmer species like tetras and doradids.

3 Guppy Guppies are live-bearing poeciliids. They give birth to fully developed fish fry. Thanks to its ease to reproduce it is one of the most favorite fish for beginners. Guppies are social fish and they feel themselves at ease in a small school with several fish.
Doradids They come from South America and are social fish that live in groups. Like many catfish they have mustache-like whiskers around the mouth that act as taste and smell organs. 4
5 Cardinal tetra This extremely sociable and peaceful fish feels at ease in schools. In order to satisfy this behavior, at least 6 or 7 fellow fish need to be kept. It is one of the most beautiful aquarium fish.
6 Tiger barb The Tiger barb is a favorite thanks to its colors and liveliness. Barbs are peaceful fish that live in schools and which prefer plenty of plants and ample swimming space. Attention: Tiger barbs like to nibble at the long fins of other fish.

Fish are what they eat! In nature fish find a wide variety of food from various sources: e.g. algae, plants, gnat larvae, insects, other fish and sometimes even their fellow fish. Their diet in an intact ecosystem is normally varied and contains everything that fish need to be healthy and vital: vitamins, minerals, proteins, carbohydrates, fibers and fats.
products contain an optimal balance of digestible nutrients. This way fish excrete less and the water is not polluted by organic wastes. But food must do one thing above all: it must keep fish healthy and active, it must help fish to develop fully their natural behavior and variety of colors. A rich and varied diet with Tetra
An aquarium cannot offer an adequate source of nutrition and there is no possibility of evasion for fish. So they are reliant on food. In principle, the food in the aquarium should be much better than that found in nature. Ornamental fish food should not contain any pathogens. In a closed environment like an aquarium any disease that ends up in it spreads rapidly and all of the aquarium’s inhabitants can fall ill. Another important factor is that the food must be completely digestible. All of Tetra’s nutrition
food is hence the best guarantee for healthy, lively and colorful fish.
Feed your fish several times a day with just as much as they need to finish completely in a few minutes.
Especially for fish fry you will find TetraMin Baby (up to 1 cm in length) and TetraMin Mini Junior (from 1 cm in length).
20
Food is not just food In order to satisfy the specific needs of every fish species, Tetra foods come in a wide variety of forms.
1. Flakes E.g. TetraMin Flakes are perfect for fish in all water zones, because they can be assimilated both at the water surface and when sinking to the bottom. This unique and fine blend of raw materials by Tetra guarantees an optimal utilization of its nutrients. Tetra flakes are durable and they do not cloud the aquarium water.
2. Crisps E.g. TetraMin Crisps Crisps are produced with a special Tetra process. They preserve much more energy than traditional flakes. If used regularly, they reduce substantially the nitrate content of the water. Suitable for all ornamental fish.
3. Granules E.g. TetraMin Granules Granules float slowly to the bottom and can be easily assimilated by the fish.
4. Tablets and wafers
Both forms of food can reach well even hidden spots - so that even shy fish can eat without being disturbed.
5. Jelly Food E.g. Tetra FreshDelica A new Tetra invention and an excellent delicacy for fish. This jelly food contains not only natural food like red gnat larvae, daphnia and brine shrimps, but also important oligo-elements, vitamins, proteins and fats. The jelly food does not contain any preservatives and it can last up to 2 years without any need for refrigeration. Tetra jelly food has a nutritional value double that of traditional flakes.
6. Natural Food E.g. TetraDelica Tetra offers sun or freeze-dried aquatic microorganisms that complete perfectly the diet of your fish. Red gnat larvae, daphnia, brine shrimps and krill are an extraordinary diet supplement. Your fish will be grateful to you for enriching their diet.
7. Sticks e.g. TetraCichlid Sticks These high-quality sticks suit are especially recommended for feeding larger fish like cichlids.
E.g. Tetra TabiMin For all ornamental fish living near the bottom such as catfish, loach or barbs skimming the bottom. Since tablets and wafers sink immediately to the bottom, the feeding place can be targeted directly. 21

Tetra-Tip Fish quickly become friendly if they are fed regularly. Already after a short period of time the fish swim directly to their feeding spot and wait for the food.
Feed sparingly Seeing fish as they eat every day is always a marvelous show. Feed sparingly - even if it is difficult - and give just as much as the fish can eat in a few minutes. These portions are easier to digest for your fish and avoid overfeeding. The food in excess decomposes in the water and damages its quality. If you feed your fish every day at the same time and in the same place, they will soon be eating straight from your hand. The daily feeding time is a good opportunity to watch fish. Feeding is very fun if you use TetraTips adhesive food tablets that you can apply to the wall of your aquarium. The fish will immediately flock to the aquarium wall to eat the food. These adhesive food tablets are made of a balanced mix of premium special flakes and top-quality freeze-dried raw materials like freshwater shrimp, brine shrimp, water fleas and gnat larvae.

Water Care Innovation Keeping a professional aquarium means imitating nature’s processes as closely as possible. The filter cleans the water in the aquarium but provides also for the balance of all of the main water values. Regular maintenance of the water is a must for any aquarium owner! Since the development of TetraAqua EasyBalance you can now choose from two options:
TetraAqua EasyBalance reduces the number of times you need to change the water of your aquarium and keeps it biologically healthy.
Regular changing of the water Change 20 - 30 % of the water with fresh water every 2 weeks. Add TetraAqua AquaSafe to the tap water to make it fit for your fish.
Thanks to TetraAqua EasyBalance you can prevent the proliferation of algae and increase your water’s buffering capacity.
Long-term water care with TetraAqua EasyBalance Instead of changing the water partially every two weeks, you can reduce the number of times you change the water with TetraAqua EasyBalance. Thanks to EasyBalance all of the important water values are maintained in a perfect balance appropriate for the fish and plants of your aquarium. It effectively stabilizes the water’s pH and CH values - it prevents a dangerous drop in the acidity - eliminates phosphates and nitrates and blocks the growth of algae. Thanks to its regular use you can keep the water of your aquarium biologically healthy for up to 6 months. Attention: The use of AquaSafe is important also for preparing tap water!

Weeks without changing water
With the Tetratec GS Glass Scraper you can clean the walls of your aquarium in no time at all.
If the aquarium water is muddy Dead plant parts, food remains and fish excrements are visible signs of water soiling. The decomposition of these organic wastes produces noxious substances in the water that you cannot see. The filter makes sure that these particles are filtered mechanically and eliminated from the aquarium. A good filter substrate offers plenty of space for useful filter bacteria that are dissolved also in the water and which break down biologically contaminants containing nitrogen. The Tetratec Komfort IN Inner Filter plus is a double guarantee for water quality: its mechanical filtering action eliminates the visible particles while the biological filtering breaks down the invisible decomposition products. The filter cartridges capture the contaminant particles in the course of time. Clean the cartridges regularly when you change the water by washing them in the aquarium water removed. This way they can maintain their filtering capacity without harming the vital microorganisms in the filter cartridges. Never use detergents
or hot tap water in any case whatsoever. It would kill the bacteria cultures. However, despite the filtering and regular partial change of the water the larger soiling particles - mulm - deposits on the bottom and in the corners of the aquarium. It’s absolutely normal and there is no reason to worry. But this mulm makes the aquarium cloudy and blurry in the long run. You should clean the bottom every now and then. Tetra offers a complete range of bottom cleaners specifically developed for the purpose and to be used while performing the partial change of the water.
TetraAqua Bactozym favors the build-up of useful filter bacteria after every change of the water.
TetraAqua CrystalWater binds floating clouding particles that are removed from the water by filtration.
The all-in-one talent: Partial water change and bottom cleaning in a single step with the Tetratec GC Komfort Gravel Cleaner.

Decomposition of contaminants Water plants absorb a part of the substances like nitrates that contaminate the water for their own growth. However, plants can manage to consume only a certain quantity of nitrate as a nutrient. If the nitrate content exceeds certain tolerance values, it can even harm the plants. Oxygen Production Aquatic plants produce oxygen during photosynthesis. If they do not have the adequate amount of
light, nutrients and carbon dioxide, plants do not grow properly and the water’s oxygen content drops. The consequences are an increased contamination of the water, poorer living conditions for fish and plants and a dangerous lack of oxygen for the fish. Taking proper care of plants is essential. Tetra has developed TetraPlant for this specific purpose: it is a plant care system that suits the specific needs of aquatic plants. Water plants absorb nutrients through their leaves and roots. For this purpose Tetra offers special root and leaf fertilizers that complement each other perfectly.
When planting and replanting, TetraPlant PlantaStart helps improve the plants’ ability to grow roots and strengthens growth with the aid of a valuable plant hormone.
No need to worry about algae An excessive growth of algae is always a sign that the biological balance in the aquarium has been altered. This is due to various factors. Three areas responsible for this phenomenon can be identified: poor water quality, incorrect lighting conditions and scarce or incorrect fertilization. The best way to fight algae is prevention. Check the number of fish in your aquarium critically. Many or large fish rapidly soil the water. Feed the fish in your aquarium to three times a day at the most one with small portions. The food should be eaten completely by the fish in a few minutes, as food remains are a source of nutrients for algae. A factor which is often underestimated is the quality of
the food you use. Low-quality and cheap foods are often poorly digested and hence lead to an intense contamination of the water. Use only brand products such as, for instance, TetraMin Crisps, because it favors a substantial reduction in the water’s contamination with nitrates and phosphates. If algae gain the upper hand, you must take fast and targeted action. TetraAqua offers a series of effective anti-algae agents.
*Use biocides safely. Always read the label and product information before use.
TetraAqua AlgiMin* is a liquid anti-algae agent with a delicate biological effect. TetraAqua Algetten* are perfect for a long-term preventive treatment. Thanks to the slow rise in the concentration of the active agents, it has an extremely mild long-term action. TetraAqua Algizit* is an effective anti-algae agent with an intense and targeted action. If used as an “emergency brake”, Algizit puts an immediate stop to algae proliferation. TetraAqua AlgoStop depot* is a highly active anti-algae agent to combat brush and thread algae.

Fish diseases In a well-cared aquarium fish diseases fortunately occur very rarely. Should your fish fall ill anyway, it is no catastrophe, because Tetra offers a range of extremely effective medicines for your fish. Well-advised and fast action plus the aid of these medicines can almost always avoid the worst. It is especially important for newcomers to the world of aquariums to know that most fish diseases are the result of poor maintenance conditions. The best way to prevent illnesses is prevention through professional aquarium care. There is no need to be an expert - just follow these easy care instructions for perfect prevention.
Tetra-Tip Fish, too, suffer from stress, which makes them vulnerable to illnesses. Avoid the following stress factors: -poor water quality -over-occupied tanks -poor nutritional variety -temperature variations -combination of incompatible species -stress after being caught and transported
Preventive Measures Food Fish need top-quality foods. Only if the food contains all of the necessary nutrients and vitamins in the right quantity and blend can fish be healthy. Low quality foods weaken the overall conditions of the fish in the long run and contaminate the water. Water Water is the vital element of fish. Water filtering, the partial change of water and the proper preparation of the water are measures that are absolutely essential for your aquarium. Without regular care for the water of your aquarium it cannot “work”. Plants Lush aquatic plants play important functions in the aquarium. Whoever takes care of his plants takes care also of the environment and prevents illnesses. Water Tests Almost every disturbance to the biological balance reflects itself in the water values. Thanks to Tetratest Water Tests you can check precisely the quality and stress on your aquarium water at any time. Diagnosis Daily health check-ups are very important. Watch your fish and check that they are behaving normally. Check also for the typical signs of an illness like rubbing, breathing problems, frayed fins or wounds.
Even the secretions from single specimens and signs of lethargy indicate illnesses.
TetraMedica GeneralTonic - effective against bacterial and parasitic illnesses.
TetraMedica ContraIck - against ich and ectoparasitic illnesses.
