Boyd Chemi-Pure Elite 11.74 oz is an advanced filter media blend designed to address key water quality issues in saltwater aquariums. This powerful combination integrates granular Ferric Oxide (GFO) with Boyd's premium pelletized activated carbon, all conveniently enclosed within a fine-mesh nylon media bag. It effectively targets and removes phosphates, silicates, and various dissolved organic compounds, playing a crucial role in controlling nuisance algae growth and enhancing overall water clarity. This elite formulation now features QuickWash Carbon, a superior pelletized activated carbon offering 30% more surface area compared to previous versions. Its harder and cleaner structure significantly reduces the potential for Head and Lateral Line Erosion (HLLE) in fish, which can be caused by fine carbon dust particles. Beyond crystal-clear water, Chemi-Pure Elite actively filters out phosphates (PO4) and silicates (SiO2), reduces nuisance algae, and eliminates dissolved organics, coppers, metals, odors, and phenols. Boyd Chemi-Pure Elite is an excellent choice for any reef aquarium hobbyist looking to simplify maintenance and achieve a more stable, visually appealing system. By rapidly removing common pollutants that lead to algae and poor water quality, it contributes to a healthier environment for corals and fish. This convenient all-in-one solution is ideal for those seeking a highly effective chemical filtration method to improve water parameters and overall aquarium aesthetics.
