Captiv Phos W Phosphate Adsorber 600 gram phosphate removing media.
Reef Basis - Captiv Phos W is a supreme quality, spherical white proprietary filtration medium particularly selected for sensitive aquarium environments. It is designed to remove free phosphates and silicates that can act a fertilizer for unwanted algae or diatoms, directly from the water. It will not kill algae and does not contain any algaecides. It is safe for all marine and freshwater life.
Directions and protocol.
Rinse well in cold filtered freshwater, preferably RO or distilled water, but tap water may be used. Warning: never rinse the first time with saltwater! Product and water may get very hot the first time it is rinsed. Wear rubber gloves and allow to cool prior to use! Discard rinse water. Place loosely in a polyester filter bag or filter chamber and position to force water flow through the beads. For best results, use a particulate prefilter ahead of the Captiv Phos W, such as filter floss or fine sponge. Use about 1 gram per gallon of aquarium capacity, or about 2/3 cupful per 100 US gallons (400 L).
