SeaChem Phosguard outperforms all competing products. PhosGuard is a high capacity and high efficiency filtration product for removing phosphates and silicates from marine or fresh water aquaria. Unlike competing products, PhosGuard is bead-shaped for optimum flow characteristics and has an exceptional porosity for enhanced capacity. PhosGuard has a working capacity to remove 20 to 60 mg/l phosphate in 100 gallons with a similar impact on silicates. It may be used continuously or intermittently, and will not release removed phosphate. PhosGuard will cause a decline in hair algae and enhance coral growth. Each liter treats up to 300 gallons. Marine or freshwater use.

Instructions: Use 1 cup for every 75 gallons. Leave product in place for 4 days, then test phosphate and silicate.
