AquaMaxx 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

Dosage
  • Rinse before use.
  • Use 1/4 to 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

PROS
Works as GFO
CONS
Super dusty and verry small particles.
REVIEW
Of the 3 other GFO's ive used this is hands down the dustiest with smallest particles. Ive been using the same bag in my sump for YEARS and this is the only GFO that even after washing and soaking leaves a ton of small gfo flakes in the bottom of the sump as they make it through my mesh bag.

REVIEW
I started using this on my 25 gallon reef tank about 6 months in after I started getting some algae blooms. . After only a few months of use in a reactor and a few good water changes the algae was no longer a problem and my phosphates levels dropped significantly.

Works great. Does not arrive all ground up and wasn't nearly as much dust as some other products.

None
REVIEW
I bought this media for my AquaMaxx GFO Reactor.
Within a 24 hour period I have seen a phosphate level of .25 reduced to almost 0 on the API test kit. It's not quite to 0 yet, but it is a lot closer than before using this media.
