PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate-buffered freshwater. It is highly porous for high capacity and bead-shaped for optimum water flow. It is spherical. Its shape allows for maximum water flow through the media. Granular phosphate removers can become compacted, dramatically limiting their capacity to remove phosphate. If the media can’t come into contact with the water, it can’t remove phosphate from it.
Features:
- Removes silicate and phosphate
- Spherical for optimal hydrodynamics
- Irreversible binding
Directions:
May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater, followed by a rinse. 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. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended. Use 85mL (1/3 cup) for every 200 L (50 US gallons) saltwater or 400L (100 US gallons) freshwater.
