Reef•Basis - Captiv Phos Fe is a supreme quality, granular ferric oxide based filtration medium particularly selected for sensitive aquarium environments. It is designed to remove free phosphates and silicates that can act as a fertilizer for unwanted algae or diatoms, directly from the water and will also remove phosphate bearing dissolved organics. It will not kill algae and does not contain any algaecides. It is safe for all marine and freshwater life.
