Tetra Biocoryn Bacteria prevents accumulation of sludge, unpleasant odours and the formation of pollutants. The formula contains effective living cleaning bacteria, which accelerate the decomposition of organic material such as food and plant remains, as well as excrements. It promotes clear water in the longterm. This has the positive effect that cleaning intervals of gravel and deco elements can be extended. Tetra Biocoryn has a 100% biological effect because it contains non-pathogenic bacterial spores from the genus Bacillus that also naturally occur in soil, in decaying plant material (e.g. compost) as well as in natural water bodies.
