Seachem PhosNet - 50g

PhosNet is a granular ferric oxide that rapidly removes phosphate and silicate from both freshwater and saltwater aquariums! PhosNet features a high surface area, high binding capacity, and high porosity, allowing stronger binding than most phosphate removing products on the market. Compared to most competing GFO products, PhosNet does not release phosphates and silicates back into your aquarium, and also offers less dust.
