Product Information
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.

I have put the recommended amount into my filter and the phosphate levels are falling but its early days (2 days in) to say whether this is due to the Phosguard or whether due to the algae. I'm waiting/hoping for the algae growth to subside. -
