Aquavitro Phosfiltrum is a specially formulated, Ultra High Capacity high-density, granular ferric oxide (GFO). It will rapidly remove phosphates and silicates from both freshwater and saltwater and will not release them back into your aquarium. It is much harder and consequently much less fragile than other GFOs, so it will not break apart into fine particles in your tank. It has the highest binding capacity of any phosphate remover on the market, so it will last much longer before it needs to be replaced. Its distinctive dark brown colour identifies it as a premier product.
50ml supplied in net bag, suggested for up to 300 litres of saltwater or 600 litres of freshwater.
For best results Phosfiltrum should be rinsed before use and places as to maximise water flow through it, but not that is tumbles against itself in the flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter.
Leave Phosfiltrum in place for 4 days then test phosphate level. If the concentration has not dropped to around 0.02ppm then replace the Phosfiltrum, 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. Phosfiltrum is not an exchange resin and does not release anything back 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.
