Seachem PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard is highly porous for high capacity and bead-shaped for optimum water flow. It outperforms all competing products. PhosGuard has a spherical shape, allowing for maximum water flow through the media. Granular phosphate removers can become compacted, dramatically limiting their capacity to remove phosphate. If the media can't come into contact with the water, it can't remove phosphate from it. PhosGuard is the only spherical phosphate remover on the market.
Caution! May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater (e.g. 100 mL of product in 200 mL water), followed by a rinse.
