🌟 Elevate your aquarium’s clarity with 4x phosphate removal power — because your reef deserves the best!
GFO HC is a premium granular ferric oxide phosphate remover that delivers nearly four times the phosphate removal capacity by volume compared to standard media. Engineered in Germany by Lanxess, it ensures ultra-pure, stable filtration media ideal for high-end reef and marine aquariums, freshwater tanks, ponds, and natural swimming pools. Its dense granules fluidize efficiently in reactors, reducing channeling and fines, while effectively binding phosphate and silica to maintain crystal-clear water and healthy aquatic life.

Absolutely rocks at keeping phosphates down in my 1300 gallon reef system! Running a bunch of Tangs in a 120L x 48”W x 36”H with a 300 gallon sump. Absolutely recommend this product to anyone wanting to Reef hard!
