Seachem PhosNet Synthetic Granular Ferric Oxide (GFO)
Seachem PhosNet Synthetic Granular Ferric Oxide (GFO)
 

Overview

* Phosphate and silicate remover for fresh and saltwater aquariums
* Rapidly lowers phosphate levels to boost aquarium water quality
* Permanent removal - will not release phosphate into your aquarium

Improve aquarium water quality with rapid, permanent removal of phosphates and silicates. Seachem PhosNet Synthetic Granular Ferric Oxide (GFO) boasts high porosity, high surface area, and high binding capacity for permanent removal of phosphates and silicates without releasing them back into your aquarium. Less dust and is easier to use than most competing GFO products. Effective use with freshwater and marine aquariums.

Use 50 g (1/2 cup) Seachem PhosNet Synthetic Granular Ferric Oxide (GFO) in a fine-mesh aquarium filter media bag such as Seachem The Bag for every 50 US gallon saltwater or 100 US gallons freshwater.

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

Use 50 g (1/2cup) 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 Test Kit 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.

General Information
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.
