Seachem PhosNet

Phosphate and Silicate Remover

  • Rapidly removes phosphate & silicate
  • Synthetic granular ferric oxide (GFO)
  • Less dust and thus is easier to use than most competing GFO products

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

Product PO4 bound
PhosGuard (Alumina Oxide) 0.87 mg/g
PhosBond (GFO and Alumina Oxide hybrid) 1.19 mg/g
PhosNet (GFO) 1.41 mg/g

For best results, PhosNet™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter.

Use 50 g (1/2 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest™ Phosphate or MultiTest™ Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosNet™, otherwise leave in place until levels begin to climb again. As long as concentrations remain under control, the product is not exhausted. Over treating is not recommended. PhosNet™ is not an exchange resin and does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. Continuous use of small quantities is better than intermittent use of larger quantities.
