Eheim Phosphate Out is a chemically acting phosphate remover, helping to inhibit the growth of algae. Eheim Phosphate Out is a special iron compound for chemical filtration. The iron binds the phosphate, removing it from the water circulation & thus reducing in stages the phosphate levels in the aquarium. In this way, algae growth in the aquarium is inhibited. If the phosphate levels begin to rise again the growth of algae starts to increase, this means that the filter medium is depleted & must be replaced.
