Has an absorbent effect i.e. harmful substances are broken down by aerobic and anaerobic bacteria who are given an exceptionally large area of colonisation (approx. 1,200 m²) by the material. Nitrite and ammoniac are absorbed efficiently, nitrate and phosphate are broken down significantly and the biological balance is assisted.
- pore channels of the sintered glass rings ensure optimal water and oxygen flow
- pore size provides ideal habitat for nitrosoma and nitrobacter bacteria
- 1 l corresponds to an inner surface of 1,200 m², or more than 4 basketball courts
- for fresh- and seawater
- sufficient for approx. 6 months in 200 l aquaria with an average number of fish
