®Phosphofiltre is designed to fix the phosphate and ammonium ions , the two main compounds responsible for the development of undesirable algae in breeding waters, but also toxic in high concentrations for aquatic animals.

®Phosphofiltre works directly at the basins bottom or in a filter bed.

®Phosphofiltre is prepared from a natural zeolite of high purity and high mechanical strength.

When used in a filter bed , the phosphate concentration after filtration is less than 0.1 ppm.
