Seachem PhosGuard Filtration

Seachem PhosGuard Filtration –

The PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria.

Although PhosGuard™ is effective in both fresh and marine water, it will operate better in sea water and the need for it is better in sea water.

It is not recommended for phosphate buffered freshwater (PhosGuard™ would remove the buffer until saturated).

PhosGuard™ is highly porous and bead-shaped to promote easy water flow through and around it, thereby increasing both its efficiency and capacity.

Key Features:

  • Removes silicate and phosphate
  • Spherical for optimal hydrodynamics
  • Irreversible binding



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 rinse before use and place so as to maximize the flow of water through it but not so that it tumbles against itself in flow.

You may 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 85 mL (1/3 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater.
