Seachem PhosGuard

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

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 defined 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.

Richard ★★★★★

My nitrates were stubbornly high until I added this. The spherical beads flow really well in my filter bag, and after three days my phosphate test finally showed zero.

Ella D. ★★★★★

I was tired of fighting silicates clouding my freshwater tank, and this stuff cleared them up in just two days. The irreversible binding gives me peace of mind that it won't release back into the water.

Samuel ★★★★☆

I was skeptical about the spherical beads making a difference, but the flow through my canister filter is definitely more even now. It cleared up my phosphate issue in about a week, and I’ve noticed less algae growth on the glass. My only small gripe is that it seems to clump a bit if you rinse it t
