Seachem PhosNet

Seachem PhosNet™ is a granular ferric oxide (GFO) with high porosity, high surface area and high binding capacity. It rapidly removes phosphates and silicates from both freshwater and saltwater and will not release them back into your aquarium. PhosNet™ exhibits stronger binding than most competing products and consequently can reduce phosphates and silicates to very low levels. PhosNet™ also offers less dust and is therefore easier to use than most competing GFO products.

Main Benefits:

• Rapidly removes phosphate and silicate
• Synthetic granular ferric oxide (GFO)
• Ideal for use in marine and freshwater
• Stronger binding and won't release phosphates and silicates back into your aquarium
