SOS

Algae, sick fish, cloudy water? Effective help for a healthy aquarium

Prepare substrate

A fertile ground with an optimal grain size is a prerequisite for healthy and lush plants growing in your aquarium.

Our Tip:

Top up the ground in the back of the aquarium later on. This has the advantage that dirt and other waste products accumulate in the front area. There they are easily visible and can be removed immediately.

Tetra CompleteSubstrate

Nutrient-rich substrate with long-term fertilisation. Activates strong and healthy plant growth.

Tetra ActiveSubstrate

Natural substrate which provides a plant-friendly soil climate and lush, healthy plant growth. The large surface and the porous structure of the water neutral clay granules offer several advantages compared to conventional gravel.

Tetra InitialSticks

Tetra InitialSticks provides nutrient-rich ground resulting in magnificent, strong aquarium plants.

Insert plants

The optimal care of your plants with nutrients is essential for strong roots and healthy plant growth.

Attention:

Plants only grow healthy if they are planted according to their needs. We recommend checking the specific needs of the plant before adding to the aquarium.

Tetra PlantaStart

Fertiliser tablets for beautiful aquatic plants. Ensures aquatic plants are specifically supplied with all essential nutrient combinations.

Add water

It is important to make tap water safe for fish because it may contain substances which are harmful to them.

Our Tip:

Use a small plate when filling the aquarium with water. This prevents the whirling of substrate.

Tetra AquaSafe

Rapidly neutralises harmful substances to make tap water safe for fish.

Test water values

Good water values are fundamental for healthy fish and plants. Test your water values before adding any fish to the aquarium.

Did you know?

With the Aquatics app from Tetra you can determine the water values quickly, easily and safely.

Tetra Test 6in1

Test strips to quickly and easily check six water quality parameters in 60 seconds

Introduce fish

Fish need a special biological environment in the aquarium. Before adding your fish, it is important to create a biologically active environment.

Fast introduction of fish made easy:

Special beneficial bacteria help shorten the cycling time of the aquarium.

Tetra SafeStart

Makes it possible to introduce fish immediately after setting up a new aquarium.

Change water and stabilise water parameters

Regular water changes are important to aquarium care. Through the exchange of water, harmful substances are removed and important nutrients are added with the fresh water. Water changes stabilise the water values in your aquarium thus restoring balance.

Important:

Optimal water values varie depending on the stocking or the aquarium size. There is no universal "optimal value" for each aquarium. Which value is optimal for your aquarium, depends on several individual circumstances.

Tetra EasyBalance

Stabilises important water values for up to six months and reduces the number of water changes.

Tetra AquaSafe

Rapidly neutralises harmful substances to make tap water safe for fish.

Tetra FilterActive

Keeps filter biologically active and reduces sludge.

Test water values

Good water values are fundamental for healthy fish and plants. For long lasting stable water values we recommend to test them once a week.

Determine your water values easily:

With the help of the Tetra Aquatics App, you will always have an eye on your water parameters.

Tetra Test 6in1

Test strips to quickly and easily check six water quality parameters in 60 seconds

Fertilise plants

Plants regularly need important nutrients in order to remain healthy with lush growth, as their leaves and roots absorb nutrients.

Herbivorous fish:

Make sure to protect your aquarium plants by limiting the number of herbivorous fish kept in your aquarium.

Tetra PlantaMin

Thanks to the special depot formula, the nutrients contained in Tetra PlantaMin stay available for plants over a period of 4 weeks. Iron, potassium, manganese and other essential trace elements provide a lush and healthy plant growth.

Tetra Crypto

Root fertiliser tablets for lush, healthy aquatic plants.

Treat sick fish

Diseases in fish can be caused by a variety of things happening in the aquarium. Quite often they originate from bacteria infections that you can quickly get under control with the help of medicines specifically designed for fish.

Important:

In the fight against fish diseases, the search for the cause is particularly important. Seek advice from your Specialist Aquatics Store if your fish aren't responding to treatment.

Fight algae

An aquarium full of algae pollutes the water, affects the biological balance and of course, the aquarium does not look good.

Tip:

Phosphates (PO₄) and nitrates (NO₃) promote algae growth. Therefore, it is particularly important to reduce the two substances in the aquarium.

(* Use anti – algae products safely. Always read the label and product information before use.)

Tetra AlguMin*

Combats effectively all types of algae. For prevention and fast action.

AlgoStop depot*

Permanently combats all types of algae. Long-term effect prevents new growth.

Treat sick fish

Important:

In the fight against fish diseases, the search for the cause is particularly important. Seek advice from your Specialist Aquatics Store if your fish aren't responding to treatment.

Reduce high nitrate values

High nitrate levels in the aquarium indicate an oversupply of nutrients - and this affects the water quality.

Caution:

Although nitrate is a plant nutrient - in concentrations greater than 50 mg / l nitrate becomes dangerous for fish.

Tetra NitrateMinus

Tetra NitrateMinus reduces the algae nutrient nitrate (NO3-) reliably and in a natural way.

Increase carbonate hardness

The carbonate hardness plays an important role in the aquarium because it stabilises the pH value and avoids drastic changes.

Caution:

The carbonate hardness is not a static value and can e.g. drop down after a water change with soft water. Test your water parameters regularly.

Tetra pH/KH Plus

Tetra pH/KH Plus allows a precise and controlled increase of carbonate hardness (KH). The pH value depends on KH and carbon dioxide (CO2) content. If the CO2 level is constant, the pH value can only be influenced by the KH value.

Eliminate cloudy water

Cloudy water in the aquarium can have many reasons and occurs for example after setting up a new aquarium.

Just to be safe:

Cloudy water is usually not dangerous, nevertheless it is advisable to check the filter and the water values. A proper ventilation could also be useful.

Tetra CrystalWater

Quickly and reliably eliminates clouding from aquarium water within a matter of hours.

Test water values

Good water values are fundamental for healthy fish and plants. If there seems to be a problem in the aquarium you should check the water values.

Test it!

Cloudy water, lifeless plants, tired fish? Before adding something into the water, a water test is useful to define the reason for your problem.

Tetra Test 6in1

Test strips to quickly and easily check six water quality parameters in 60 seconds

Boost lifeless plants

Lifeless plants with yellow or almost transparent leaves don´t look good in your aquarium. In addition, plants have an important role in the ecosystem of the aquarium. Therefore it is important to maintain healthy aquarium plants.

Let there be light!

Sometimes your plants do not only need nutrients but also need some light. Try to boost your plants by providing them with enough light and check the lightning in your aquarium.

Tetra PlantaMin

Tetra CO2 Plus

CO2 is an essential nutrient for a healthy and lush plant growth. Tetra CO2 Plus adds carbon to the water in a form ready accessible for plants.
