Dr.G's Phosphate Remover is the purest form of super absorbent "Ferric Oxide" available. It does not leach aluminum into your aquarium, will not affect pH, or hardness and will last for several months. Replace when Phosphate levels start to rise above 0.02 PPM.
Directions: Use in Media Bags or Fluidized Bed Reactors (Media bag included). Do not pulverize the granules. Add the desired amount to filter bag. Rinse (with the contents inside) with cold RO water until water runs clear of dust and resin particles. Place the Media Bag in your filtration system, ideally 'sandwiched' inside two filter pads. Dr. G's Phosphate Remover can also be used in Phosphate Reactors/Fluidized Beds.
Dosage: Saltwater: Use 1 Gram per Gallon of water, 150 grams will treat up to 150 gallons (567.81 Liters) of water, Freshwater: 1 Gram will treat 2 Gallons of water, 150 grams will treat up to 300 gallons (1135.62 Liters) of water. In aquariums with high populations of fish, dosage can be increased safely x 3 times. At higher doses it could cause a drop in alkalinity. Monitor alkalinity and correct if necessary. The active life of this product will depend on the phosphate concentrations in your system, but it will remain active for several months.
