Seachem Aquarium accessories Pond Phosguard

Eliminates phosphates and silicates. Spherical for optimal hydrodynamics. Does not discharge. Pond PhosGuard is an ecologically sound approach to phosphate control in ponds. It is an adsorbent filter that eliminates phosphates, silicates and organic nutrients. 1 liter treats over 1200 l. Pond PhosGuard is spherical. Its shape allows maximum water flow through the media. Granular phosphate extractors can become compacted, severely limiting their ability to remove phosphate. If the media can't come into contact with the water, it can't remove the phosphate. Pond PhosGuard is the only spherical phosphate remover on the market. 1 l treats 1 l.
