Tetra Crusta AquaSafe

Tetra Crusta AquaSafe dissolves quickly and makes tap water habitable in an instant.

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

Keeps filter biologically active and reduces sludge.

Tetra EasyBalance
Stabilises important water values for up to six months and reduces the number of water changes.
Tetra Vital
Promotes vitality, well-being and the natural colouring. TetraVital adds essential vitamins, minerals and trace elements from the natural habitat of the fish that tap water cannot provide, or which are used up in the aquarium. This creates an almost natural environment, where fish can feel at ease and develop their natural colouring.
Tetra Bactozym
Tetra Bactozym speeds up biological activity in the aquarium. Organic colloids naturally cover filter material and all surfaces with an invisible film to promote the colonisation of beneficial filter bacteria. This means that the first stock of fish can be added just 24 hours after setting up a new aquarium. Both water changes and filter maintenance can be performed without any serious loss of bioactivity.
Tetra Biocoryn

Prevents the build up of sludge and unpleasant odours.

Tetra Biocoryn contains highly active enzymes and bacterial concentrates, which decontaminate the water and accelerate the decomposition of organic material, such as uneaten food, fish waste and dead plant material. The special formula, which offers immediate, long-lasting results, safely breaks down mulm and prevents further accumulation of sludge. Unpleasant odours are eliminated and the water becomes clear and healthy.

Tetra NitrateMinus

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

Tetra NitrateMinus Pearls
For the permanent reduction of nitrate content when setting up a new aquarium. It removes an important algae nutrient, leading to a long-term improvement of the water quality, reducing care requirements.
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.
