Seachem Phosguard 250mL

PhosGuard™ is a product that can quickly eliminate phosphate and silicate from freshwater and marine aquariums. While it is effective in both types of water, it works better in salt water. However, it is not recommended for use in freshwater that has a phosphate buffer since it will remove the buffer until it becomes saturated. PhosGuard™ has a highly porous and bead-shaped structure that promotes efficient water flow and increases its capacity to filter impurities.
