SeaGel is a blend of MatrixCarbon and PhosGuard. 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. May also be used in freshwater that is not phosphate buffered.

Sizes: 100 mL 250 mL, 500 mL, 1 L, 2 L, 4 L, 20 L

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. 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.

Use 500 mL for each 300 - 450 L (80 - 120 gallons*). Use in a filter bag. Rinse in freshwater before use. Use caution, since product will fizz and heat on initial wetting. SeaGel will function 3 - 4 months. May also be used in freshwater that is not phosphate buffered.
