Seachem PhosGuard Phosphate/Silicate Control

SeaChem PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate-buffered freshwater. SeaChem PhosGuard is highly porous for high capacity and bead-shaped for optimum water flow.

• Removes phosphate and silicate from fresh and saltwater systems
• Highly porous and bean-shaped for maximum absorption and water flow
• Causes a decline in hair algae and enhanced coral growth

SeaChem Phosguard outperforms all competing products. PhosGuard is a high-capacity and high-efficiency filtration product for removing phosphates and silicates from marine or freshwater aquaria. Unlike competing products, PhosGuard is bead-shaped for optimum flow characteristics and has an exceptional porosity for enhanced capacity. PhosGuard can 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.
