GFO Granular Ferric Oxide - AquaMaxx

Please make a selection



AquaMaxx Granular Ferric Oxide (aka GFO) is an adsorbent filter media that helps to remove phosphate from the aquarium water without leaching it back into the water.

Having GFO in your filtration system reduces the risk for nuisance algae growth, which can quickly build up as fish waste and leftover food breaks down.  Algae will get out of hand if left unchecked as high phosphate levels help to feed the algae, and also inhibit stony corals` calcium uptake to form new skeletal structure.

AquaMaxx GFO can be ran within a media reactor for maximum efficiency, placed in a media filter bag and placed where water may flow through it in the sump, hang-on-back filter, or canister filter.

Use Guidelines:

  • Rinse media before use
  • Use 1/2 a cup per 50 gallons of saltwater aquarium volume
  • Use 1/4 a cup per 50 gallons of freshwater aquarium volume
  • Test phosphates regularly and replace media when levels begin to rise (1 - 3 month range)
  • Note: Alkalinity levels may drop when used, so should be monitored and adjusted as needed.

Available sizes: 1 lb / 2 lbs / 4 lbs

What phosphates?

PROS
Works well in reducing phosphates
CONS
Nothing.
REVIEW
I've been running Aquamax GFO for years and it simply works great. I tried other more expensive brands and didn't notice the difference so I'll stick with AM considering the value and quantity you receive.

It’s Gfo, gets the phosphates out
reviewerbadge
PROS
Takes out the phosphates
CONS
Need some kind of reactor and pump to tumble it for most effective use
REVIEW
Gfo works. Been using it for years in a small reactor with a pump to tumble it as a normal part of water maintenance. Phosphates and nitrates are always something you need to manage. This will definitely help on the phosphates.

REVIEW
In my opinion one of the best GFO options out there! Last super long, doesn’t breakdown as fast as others and gets the job done! I use about 9oz in my 120 gallon mixed reef and it last about 2-2.5 months!
