Seachem SeaGel is a powerful blend of Seachem's MatrixCarbon and PhosGuard, designed to dramatically improve water quality in reef and marine aquariums. It works by effectively removing a wide range of impurities including organic compounds, color impurities, phosphate, silicate, toxic metals, and various acids, leading to a clearer, healthier aquatic environment. This unique filter media combines MatrixCarbon, an ultra-capacity carbon, with PhosGuard, a potent remover of phosphates and silicates. Both components are engineered into bead shapes to ensure optimal water flow characteristics and efficient penetration within the filter. A key advantage of this blend is that PhosGuard actively compensates for any minute leachable phosphate from the carbon, ensuring comprehensive filtration without compromise. Seachem SeaGel is ideal for reef and marine aquarium enthusiasts seeking a comprehensive solution for maintaining pristine water quality and a thriving ecosystem. Its synergistic blend is particularly beneficial for those looking to combat algae growth by controlling phosphates and silicates, while simultaneously achieving crystal-clear water. It can also be used in freshwater aquariums that are not phosphate buffered, offering versatile application for advanced hobbyists.
