PHOSPHATE STOP, high-efficiency phosphate adsorber, quickly and efficiently removes phosphate and other substances from saltwater, freshwater, or pond water. Optimal for reef aquariums, Phosphate Stop will not release adsorbed phosphate and other substances back into the water, even after the media is exhausted.
Phosphate Stop is iron hydroxide-based and will not affect tank pH.

REDUCES PHOSPHATE AND OTHER ORGANICS: Removes phosphate, silicate, arsenic, and other dissolved organic waste.

HELPS PREVENTS ALGAE: Reduced levels of phosphate and other substances helps prevent algae formation.

IMPROVES CORAL HEALTH: The reduction of biologic retardants leads to increased coral growth, better polyp extension, and enhanced coral colors.
