Kolar Labs Crystal Cal Activated Carbon and GFO HC - High Capacity Bayoxide E33HC Phosphate Remover - for Fish Tanks, Aquariums & Ponds, 350g

Fast-Acting & EffectiveCrystal Cal Activated Carbon was painstakingly sourced by our partners at Calgon Carbon and is made specifically for aquarium water filtration. It features a sub-bituminous coal base with optimum pore structure to help remove colors, tannins, odors, medications and other common contaminants from aquariums and ponds.In aquariums, the water’s phosphate level plays an important role. Excessive phosphate causes cloudy water 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.
