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.Dosage Rinse before use. Use 1/2 cup per 50 gallons for saltwater aquariums. Test phosphate levels and replace media when levels begin to rise (approximately every 1-3 months). As with all ferric oxide media, alkalinity levels may drop when used. Be sure to monitor alkalinity and adjust as needed

Don't buy it.
Dont order this. My phosphates went up when I started using this. Unplug my reactor and my phosphates went down. Buy real GFO, not this powder crap. Only reason I'm leaving this review is I'm back on Amazon looking for better gfo.

Don’t recommend
This product is very fine and leaves a brown film on the inside of your tubes.Threw the product away, replaced the tubing to media reactor and ordered real GFO from Bulk Reef Supply.
