  1. Hey Folks,
    I have a question about using RO and RO/DI water. Which is better ? I currenlty own a RO/DI. Will there be any draw backs using RO/DI compared to RO ? will I be exporting certain nurtients that lacks the need for MJ?
  2. You can use both of them, RO/DI, but not sure it is really worth the hassle, why not just use your tap water?
    good luck
  3. thnxs for the reply Mcurry. I have a marine tank full of hard water is critical to my tank. Since I have them why not use them? just curious if it was really important.
