High performance phosphate and silicate control for marine or freshwater aquariums. Seachem PhosGuard rapidly removes inorganic and organic phosphate and prevents buildup in your aquarium. Highly porous, high capacity beads resist compaction for optimum water flow essential for effective aquarium phosphate removal. 100ml treats 60 gallons.
Note: PhosGuard is not recommended for phosphate buffered freshwater.
PhosGuard - 100mL treats 60 gallons
May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater, followed by a rinse. For best results, PhosGuard™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended. Use 85 mL (1/3 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater.
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 mg/L, 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. Over treating is not recommended. PhosGuard™ is not an exchange resin and 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.
NOTE: These directions supersede all other prior packaging.
Use 200 mg Safe (scoop) per each 200 L (50 gallons) as needed to reduce chlorine and chloramine or per 50 L (13 gallons) for ammonia.
All other sizes
Use 1.25 g (1/4 tsp.) for every 1,250 L (300 US gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 US gallons) for ammonia. For precise dosing, use the Seachem Digital Spoon Scale.
