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.
Add 1 capsule for every 50-60 litres of aquarium water once per week. Also use the product each time the water is changed.
