Simplicity GFO - 1.0 lb (16 oz)
Simplicity GFO (granular ferric oxide) safely adsorbs phosphates, silicate, and dissolved organics, improving coral health and coloration and reducing nuisance algae.
GFO binds and traps excess phosphate, silicate, and other chemicals in the water column, enhancing water quality and clarity.
In proper concentrations, phosphate is essential to coral metabolism and growth. However, in high concentrations, phosphate cripples coral growth and fuels algae.
It locks away adsorbed phosphate, silicate, and dissolved organics within the media and prevents them from leaching back into the aquarium water.
