Seachem PhosGuard is a highperformance phosphate and silicate remover for both freshwater and marine aquariums. Its spherical, highly porous aluminaoxide media binds phosphate and silicate irreversibly, helping to control nutrient levels that fuel algae growth and reduce water clarity. PhosGuard works rapidly and can be used in a variety of filtration systems to support cleaner, healthier water conditions.
