PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard is highly porous for high capacity and bead-shaped for optimum water flow. It outperforms all competing products. 500 mL easily treats over 150 gallons*. This product is sold by volume. Cited weight is minimal weight.
- Caution: When wetting the product for the first time, it should be made wet with twice its volume of freshwater by adding the product to the water. Avoid adding water to the product. Avoid using marine water for the initial wetting. Adding marine water to the dry product may generate sufficient heat to boil the water. Freshwater generates much less heat and adding the product to the water allows the heat to dissipate safely.
- Benefits: 1. Removes silicate and phosphate.2. Spherical for optimal hydrodynamics.3. Irreversible binding.
- Compatible Filter Type: Canister Filter; Media Chamber; Box Filter; Trickle Filter
