SeaGel is a blend of MatrixCarbon and PhosGuard and is is optimized specifically for aquaria where organic color body and acid removal is required without the introduction of phosphate. MatrixCarbon is an ultracapacity carbon for the removal of organic and color impurities. PhosGuard is a powerful remover of phosphate, silicate, toxic metals, and acids. Both components are bead shaped for optimum water flow characteristics and penetration. The components enhance each other and are ideal for reef and marine use. SeaGel may also be used in freshwater that is not phosphate buffered.

Although MatrixCarbon has the lowest detectable leachable phosphate content of all major carbon brands tested, some phosphate is still released. Adding PhosGuard to the mix compensates for this.
