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.
Directions
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 of a filter bag is recommended.
Use 50 g ( ½ 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 MultiTestPhosphate 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.
