AquaMaxx Phosphate Out is a granular ferric oxide adsorptive filter media that removes phosphate from aquarium water. Phosphate is a fuel for algae growth and can also inhibit a coral`s ability to utilize calcium in water. Phosphate Out does not leach phosphate back into aquarium water after it has been absorbed by the media.
For best results, use AquaMaxx Phosphate Out inside a canister, hang-on back or other aquarium filtration system. Using a filter media bag is strongly recommended.
Phosphate Out can also be used in fluidized (up-flow) media reactors. A ball valve is required to regulate a slow flow rate through the filter to prevent granules from becoming pulverized.
1/4 gallon = 1 quart = 4 cups of media
