PhosBan Granular Ferric Oxide Hydroxide (GFO) is a highly effective filter media designed to adsorb phosphates, silicates, and dissolved organic compounds from both saltwater and freshwater aquariums. This powerful media binds these undesirable substances permanently, preventing them from leaching back into the water column and ensuring long-term water quality.

This specific package contains a generous 1,200 grams (approximately 2.65 lbs) of PhosBan Media, providing a substantial supply for extended use. A quantity of 150 grams is capable of treating up to a 150-gallon aquarium for several months, with the exact duration depending on the initial phosphate levels and bioload. It is recommended to replace the media when aquarium phosphate levels begin to show an increase.

PhosBan GFO Media is an indispensable tool for any serious reef aquarist or freshwater hobbyist seeking to maintain pristine water conditions. By consistently reducing phosphates and silicates, it helps to control nuisance algae growth, promote vibrant coral health, and create a more stable and thriving aquatic environment. It offers an easy, efficient, and permanent solution for crucial water parameter management.
