Designed for both saltwater and freshwater environments, it prevents algae growth and protects coral health by maintaining phosphate levels below 0.05ppm. Manufactured in Germany by Lanxess to rigorous purity standards, this 7lb, 1-gallon bucket of ultra-pure media is mechanically stable, reduces fines, and works seamlessly in reactors and various filter types, making it the go-to choice for high-end aquariums, ponds, and even natural swimming pools. ## Description In aquariums, the water’s phosphate level plays an important role. Excessive phosphate causes increased algae growth and poor fish health in freshwater and saltwater aquariums and serious harm to corals in saltwater reef aquariums.Our high-capacity GFO(granular ferric oxide) has nearly four times the phosphate removal capacity by volume in saltwater as other phosphate removers . It is denser, so it fluidizes well in a reactor with reduced channeling and is more mechanically stable for fewer fines after rinsing. Even when severely stressed, with GFO HC, the water remains clear and does not discolor during treatment.In addition to phosphate, GFO HC also removes silica. It strongly and effectively binds both phosphate and silica for lasting removal from your aquarium. Start with a standard dose of 1 gram/gallon and add or change media when phosphate levels start to rise or algae increases. For best results, do not allow phosphate levels to test above 0.05ppm.GFO HC can also be used as a swimming pool additive to manage phosphates by addition to swimming pool filters. It is a non-toxic alternative to other phosphate management approaches. It works in natural swimming pools as well!Bayoxide E33HC GFO is made by the same trusted German manufacturer, Lanxess, that has been making Bayoxide E33HC GFO products for the aquarium industry to rigorous quality, performance, and drinking water purity standards for years.
