Seachem Laboratories PhosGuard Phosphate and Silicate Remover 1ea/250 ml
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.
Directions
1. Add Seachem PhosGuard to your aquarium filter. For every 150 gallons of water, use over 500 ml of PhosGuard. For example, for a 450-gallon aquarium, use at least 1500 ml of PhosGuard. 2. PhosGuard can be used continuously or intermittently. If used intermittently, it should be left in the filter for at least 4 days for each use. 3. PhosGuard does not release removed phosphate back into the water. 4. Using PhosGuard will cause a decline in hair algae and enhance coral growth in your aquarium.
