Tetra Goldfish AquaSafe
Fast dissolving Tetra Goldfish AquaSafe turns tap water immediately into fish safe nature-like aquarium water. The new formula promotes healthy fish through a unique mix of vitamins, natural biopolymers as well as trace elements. Goldfish AquaSafe creates water that makes fish feel just like they do in their natural habitat.
Tetra SafeStart
Makes it possible to introduce fish immediately after setting up a new aquarium.
Tetra FilterActive
Tetra FilterActive adds highly effective live bacteria and thus promotes permanent biological activity in the aquarium.
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.
