Lynn,
I know you have multiply DT's I do not remember the gallonage thou. I run 2 32gal brutes, I do a 30gal WC every 2 weeks, I use abuot 30gal of RO/Di in that period for my MU/Kalk mix. I have never had an emergency to do a salt water change, and yes there is always the first time! 4 days before the WC I fill my 7gal Kalk jug, and any RO/Di goes into the salt brute and just keep makeing RO/DI and fill both, then I do the 30gal WC and leaves me with 30gal RO/DI in the other, Yes I should refill the WC ain case of an emerency, but as I said never needed it yet. But I should refill it just in case.
