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 beadshaped for optimum water flow. It outperforms all competing products. 500 mL easily treats over 150 gallons

DIRECTIONS For best results PhosGuard should be placed so as to maximize the ow of water through it. It may be used in a canister filter box filter or any high ow area of a trickle filter. In some situations it may be necessary to use in a filter bag. Use 250 mL 1 cup for every 300 L 75 gallons. Leave product in place for 4 days then test phosphate or silicate concentrations with either MultiTest Phosphate or MultiTest Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mgL then replace the PhosGuard otherwise leave in place until levels begin to climb again. As long as concentrations remain under control the product is not exhausted. Each 500 mL of PhosGuard treats over 600 L 150 gallons i.e. will remove up to 30 mgL phosphate in 600 L 100 gallons of water depending on the initial phosphatesilicate concentrations and the current biological load. Over treating is not recommended. PhosGuard is not an exchange resin it does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed dried and returned to service until exhausted. Continuous use of small quantities is better than intermittent use of larger quantities.
