## Features

- REMOVES SILICATE AND PHOSPHATE: PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria.
- IRREVERSIBLE BINDING: PhosGuard will not release phosphates or silicates back into your tank or aquarium due to its ability to exhibit strong binding capabilities, consequently reducing phosphates and silicates to very low levels.
- USE: Although PhosGuard is effective in both fresh and marine water, it will provide optimal results in sea water and the need for it is better defined in sea water.
- FILTRATION: PhosGuard is highly porous and bead-shaped to promote easy water flow through and around it, increasing both its efficiency and capacity.
- DIRECTIONS: Use 85 mL (⅓ cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. 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.
