We recommend leaving the resin up to one week or until no further decrease of nitrate is observed (via test kit). After which we recommend to remove the resin and to recharge it immediately to prevent biological fouling of the resin.

The type of filter, the turn over rate of water, and concentration of nitrate will influence greatly the speed at which the resin will remove the nitrate and become saturated.

If the resin was left for too long, clean thoroughly the resin with tap water. Than, recharge the resin until the brine solution stay clears (not yellowing). Long exposure to the filter may indeed clog the pore of the resin. The efficacy will be affected.

If the resin did not seems to be efficient in Mr. Lloyd's tank. a few things may have happened.

1) The resin has a greater affinity with nitrite. So, if significant nitrite level is present it will affect the quantity of nitrate removed.

2) What was the nitrate level prior the beginning of the treatment? When the nitrate level is near the high end of the test kit, as for example the Nutrafin Test Kit is 110, it may be impossible to make distinction between a level of 110 ppm from a level of 150 ppm. However, in this case, even if the resin does remove 25 ppm of nitrate, the end reading will be 125 or 110 ppm. It may be necessary in some cases to make multiple recharges/ filtration cycles before ‘visualizing’ a difference.

3) Salt content of water. When there is a high level of salt of present in water (such as with water softener apparatus) it may decrease the speed at which our resin works (chloride competes with nitrate onto the resin).

It is recommended, when tests reveal a high level of nitrate in a tank, to create a test solution using a dilution with nitrate free dechlorinated water. 1 cup of tank water in 9 cups of nitrate free dechlorinated water will dilute the tank water by 10. So an initial test with water with 150 ppm (but originally reading 110 ppm as the maximum with a Nutrafin Test Kit) will now be read as 15. By using this procedure with subsequent tests, it is then possible to keep track of the reduction of nitrate.
