The Kolar Filtration HC Bayoxide GFO 35 lbs Bucket is a premium granular ferric oxide phosphate reducer designed to combat tough algae growth in both fresh and saltwater aquariums. This high-capacity filter media works by rapidly and effectively eliminating the phosphate food source that fuels nuisance algae, which can otherwise cause significant harm to delicate fish, coral, and other aquatic life within your tank environment.

This ultra-pure GFO media boasts an impressive capacity, absorbing up to twice as much phosphate as standard removal media, ensuring longer-lasting efficacy and clearer water. Beyond phosphates, it also efficiently removes silicates, arsenic, and various heavy metals, contributing to a purer aquatic ecosystem. Its low fines and dust content, coupled with high hardness and density, make it highly resistant to abrasion, ideal for continuous use in demanding applications like media reactors.

Best suited for discerning aquarists maintaining reefs and high-end marine fish tanks, this powerful phosphate reducer creates a healthier and more stable environment for all aquatic plants and animals. It is safe for use in all types of aquariums, including reef tanks, ponds, and aquaculture facilities. This versatile media performs exceptionally well when deployed in reactors, filter socks, canister filters, and standard filter cartridges, providing flexibility for various filtration setups.
