Phosphate Controller - Water Dispersible Powder of an Ionically Modified Clay
PKO is a type of bentonite that removes phosphate from freshwater and marine aquariums by creating a new insoluble element that binds to interstitial phosphate in the sediment. It is safe for use in aquariums and does not generate ecotoxicity.
Highlights:
Removes Phosphate from water within three hours of application
It is not an algaecide
One kilogram of PKO removes more than 30 grams of PO4 (1 gr - 0.34 ppm)
PKO dosages depend on water phosphate levels and external sources of phosphorus in the aquarium
Can be used with a dosing pump (1:4 ratio with RO water)
