Active absorbent to remove phosphate in fresh and salt water aquariums

In an aquarium, phosphate results in over fertilisation, which in turn produces excess alga growth. antiphos is an active absorbent for the removal of phosphate from fresh and salt water aquariums. antiphos is based on natural zeolite, which has been chemically treated so that it binds phosphate. When the material is saturated it is removed and thereby completely removes the phosphate from the aquarium.
