Excessive Anion DI media usage

[TheReaperOfMars]

Sorry, but that is not an explanation for unbalanced consumption of the anion resin and not the cation resin. The total positive charges in water will exactly match the negative charges, and they thus deplete both resins.

The only way one can get depletion of only one or the other resin is if the water is very acidic or very basic (not typical of drinking water) or if there are uncharged ions that become charged one way or the other in one of the resins. CO2 fits that latter description, is very common in well water, and is nearly always the cause of selective anion depletion.

Fair point. I have the CO2 problem with my well water as well. Just haven't worked out a good solution yet. Still trying to figure out how to push the correct flow through the DI resin after aeration.

I use a Tunze ATO pump

I use lye to regenerate the anion.

Take 45 minutes and back to running.
