PhosGuard - 1L
Seachem PhosGuard The top of the line filter media is scientifically designed to quickly remove harmful phosphates and silicates from both freshwater and saltwater aquariums. The media was created with a specially designed spherical shape to promote ideal hydrodynamics and the increased porosity of the beads helps to improve both the efficiency and the capacity to bring aquarium water to the proper parameters. Despite being effective for both freshwater and saltwater aquariums, Seachem PhosGuard actually operates better in marine environments where use is more often required. Comes in a 1 liter container.
