Seachem SeaGel is a convenient and powerful filtration media blend designed to clarify and purify your aquarium water. It combines MatrixCarbon, an ultra-capacity carbon for removing organic and color impurities, with PhosGuard, a potent remover of phosphate, silicate, toxic metals, and acids. This synergistic mix provides comprehensive chemical filtration in a single product, promoting a healthier environment for your marine life.

The components in SeaGel are bead-shaped to ensure optimal water flow characteristics and deep penetration, maximizing contact time and efficiency. A single 500 mL container is sufficient to treat 80 to 120 gallons of aquarium water and will continue to function effectively for three to four months. For proper use and easy replacement, SeaGel must be placed inside a filter media bag within your filtration system.

This product is ideal for reef and marine aquarium hobbyists seeking an effective, all-in-one solution for controlling both organic waste and phosphate levels. Its dual-action formula simplifies filtration maintenance by addressing multiple water quality issues simultaneously. While perfect for saltwater setups, SeaGel can also be used in freshwater aquariums that are not phosphate buffered, making it a versatile choice for advanced aquarists.
