Seachem PhosGuard 100 mL

Seachem PhosGuard is a high-performance phosphate and silicate remover designed for both freshwater and marine aquariums. Its highly porous, spherical aluminum-oxide media allows water to flow efficiently through the material, helping it rapidly bind unwanted phosphate and silicate. This can help control conditions that contribute to nuisance algae and maintain cleaner aquarium water.

Key Features

• Rapidly removes phosphate and silicate
• Suitable for freshwater and marine aquariums
• Highly porous media for strong adsorption capacity
• Spherical bead shape provides excellent water flow and hydrodynamics
• Irreversibly binds phosphate and silicate, so they are not released back into the aquarium
• Can be used in canister filters, media chambers, box filters, and high-flow filter areas
• Best used inside a filter media bag
• 100 mL pack size
• Ideal for helping manage excess nutrients and algae-related water-quality issues

Recommended Dosage: Use approximately 85 mL per 200 L saltwater or 400 L freshwater. Rinse and pre-wet with freshwater before placing it in the filter.
