Seachem PhosNet Synthetic GFO - Phosphate & Silicate Remover for Fresh and Salt Water 4.4 lb

REMOVAL: Seachem’s PhosNet is a granular ferric oxide (GFO) with high porosity, high surface area, and high binding capacity. It works to rapidly remove phosphates from silicates from both freshwater and saltwater.

BINDING: PhosNet will not release phosphates or silicates back into your tank or aquarium due to its ability to exhibit strong binding capabilities, consequently reducing phosphates and silicates to very low levels.

USE: The reduction of dust produced by PhosNet makes this GFO product easy to use every time you are wanting to remove phosphate from your aquarium.

FILTRATION: 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 and a filter bag is recommended.

DIRECTIONS: Use 50g (½ cup) of PhosNet for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Leave PhosNet in place for 4 days, then test phosphate or silicate concentrates. As long as concentrations are above 0.02 mg/L, the product is not exhausted as over treating is not recommended.
