EHEIM phosphateout is a special iron compound for chemical filtration. The iron binds the phosphate, removing it from the water circulation and thus reducing in stages the phosphate levels in the aquarium. In this way algae growth in the aquarium is inhibited. If the phosphate levels and consequently the growth of algae starts to increase, this means that the filter medium is depleted and must be replaced. 390 grams size.
