Seachem PhosGuard 500ml – Phosphate & Silicate Remover Media

Seachem PhosGuard™ 500ml is a high-capacity filtration media designed to rapidly remove phosphate and silicate from both marine and freshwater aquariums. Its highly porous, bead-shaped aluminum oxide structure ensures maximum contact time and excellent water flow without clumping or channeling.

PhosGuard™ helps prevent nuisance algae growth and supports healthier coral and fish environments by reducing excess nutrients efficiently. Extensive controlled testing has shown that under normal reef conditions (pH ~8), PhosGuard™ does not release detectable soluble aluminum, making it safe for reef aquariums when used as directed.

This non-leaching, non-exchange filtration media can be dried and reused until exhausted, offering consistent performance and excellent value. Ideal for use in canister filters, media reactors, and high-flow filter chambers, Seachem PhosGuard™ is a trusted solution for nutrient control, available now from Reef freaks.
