Lowering RODI pH
I just purchased a 4 stage RODI from BRS. I have an RO system for my home that is giving me 6.6pH water which is great but not designed to produce the quantity needed.
After dosing the BRS unit to a dKH and dGH of 4, the PH is 7.4-7.6. Should I be aeriating the water over night after dosing an retest? As I understand the DI portion should give me a neutral pH but 6.6 is the sweet spot for me. Not sure why itís higher. Iíve run about 30 gallons through the unit before testing.
