Boyd Enterprises Chemi-Pure Elite Filter Medium

Boyd Enterprises Chemi-Pure Elite Filter Medium allows your fish to live a healthier and longer life (up to 4 times longer). Works equally well in marine or freshwater aquariums to remove heavy metals, copper, phenol, ammonia, and other nitrogenous waste. Helps keep pH at a consistently safe range and your water sparkling clear. Fantastic for use with African Cichlids and Discus. Chemi-Pure Elite adds ferric oxide to the original Chemi-Pure formula to also remove phosphates and silicates, making it the only complete choice for filtering any kind of aquarium.
