Phosguard 250 ml

PhosGuard rapidly removes phosphates and silicates from marine and freshwater aquariums. Although PhosGuard is effective in both freshwater and saltwater, it performs better in saltwater and is more critically needed in saltwater.

Key Features:

• Removes silicates and phosphates
• Spherical shape for optimal hydrodynamics
• Irreversible binding

Instructions:
May generate heat upon initial contact with water. Pre-moisten by adding it to twice the amount of fresh water, then rinse. For best results, rinse PhosGuard before use and position it to maximize water flow through it, but not so that it tumbles against itself in the flow. It can be used in a canister filter, media chamber, box filter, or any high-flow area of a flow filter. A filter bag is recommended. Use 85 ml (one-third cup) for every 200 liters (50 US gallons) of saltwater or 400 liters (100 US gallons) of freshwater.
