    The pH of RO/DI water is basically neutral and quickly takes on the characteristics of whatever you add to it or it is added to. It has no effect on the tank with small top offs and when doing a water change the RO/DI takes on the pH of the salt mix you are using.
    Some will say RO/DI is acidic but in reality it does not have enough ions to accurately measure the pH so it is considered neutral.
