Seachem PhosGuard 100ml – Phosphate & Silicate Remover for Aquariums

Seachem PhosGuard™ 100ml is a fast-acting, high-capacity phosphate and silicate remover designed for both marine and freshwater aquariums. Made from highly porous, bead-shaped aluminum oxide, PhosGuard™ maximizes water flow while efficiently reducing excess nutrients that fuel nuisance algae and harm coral health.

Unlike many competing products, PhosGuard™ does not leach phosphate or silicate back into the water and is safe for reef systems when used as directed. Extensive controlled testing has shown no detectable aluminum release under normal reef conditions, making it a trusted choice for reef keepers seeking crystal-clear, nutrient-controlled water.
