Rapidly neutralises harmful substances to make tap water safe for fish.
Makes it possible to introduce fish immediately after setting up a new aquarium.
Stabilises important water values for up to six months and reduces the number of water changes.
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 ToruMin instantly creates water that is identical to naturally occurring tropical water (known as black water), just like the water that fish encounter in their natural habitat. Peat extracts convert the aquarium water into crystal-clear tropical water where fish can feel at ease and fully display their own specific behaviour and characteristics.
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.
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.
Quickly and reliably eliminates clouding from aquarium water within a matter of hours.
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.
