The Fluval Nitrate Remover resin (FNR) can and should be recharged until the ion exchange capacity significantly drops. This can be assessed with a nitrate measurement before adding FNR and up to three days after. Since there is no visible change in the resin appearance, the only way to really define the efficiency of the recharges is to test both before and after.

What fouls the resin and makes it inefficient at removing the nitrate is that a fine organic and bacterial biofilm will obstruct the micropores of the resin. So, leaving the FNR the shortest amount of time possible into the filter and immediately recharging it into brine will prolong the effective life of the resin.

After recharging cycle is done (the brines stays colourless), leave the resin in fresh brine.

It is best to use the nitrate remover for a short period of time, using a nitrate test kit to determine when the media has been fully loaded, as there is no actual physical appearance change. Then recharge it immediately to prevent the growth of organic microfilm over the pores. Once the nitrate remover is recharged to cpacity, leaving the brine colourless when added, then move the media into a fresh brine solution for storage until required.
