    Default What is your TDS reading before and after RO and DI

    wow I just replaced my DI. It seems like I just replaced last year. lol

    My readings after replacing DI are 225 in then 17 RO out then 0 after DI.

    I do 40 gallons sw changes on both tanks every 10 days, then of course ATO.

    Im thinking I need some new membranes. any ideas lmk

    Seems fast to run out of DI.
