Aquarium filter accessories Phosguard 1 L

Rapidly eliminates phosphate and spherical silicate for optimum hydrodynamics. Adsorbs 0.87 mg phosphate per gram of media. PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquariums. Although PhosGuard is effective in both fresh and salt water, it works best in salt water. It is not recommended for freshwater with a phosphate-based buffer (PhosGuard will strip the buffer to saturation). PhosGuard is highly porous and pearl-shaped to promote easy water flow through and around it, increasing its efficiency and capacity. 1 l treats 1200 l.
