Seachem PhosGuard removes phosphates and silicate from both marine and freshwater aquariums. It has a highly porous quality and spherical shape that allows for maximum water flow and the best results. It is not recommended for use in phosphate buffered freshwater aquariums.
PhosGuard will not leach any toxins, phosphates or silicates back into the water. Simply add the correct amount to a filter bag, or directly to the filter canister, drip tray, sump or box filter. Make sure to place it in an area of high flow, for the maximum water exposure.
