RO/DI water vs other
Quick question. I'm still in the paper phase of setting up a low tech tank. I'm getting all of my ducks in a row before I start purchasing items. Because I have a reef tank, I have a good RODI filter. Should I use filtered water on a planted fresh water tank? Would the discharge water be ok to use? Currently, and this will change as my wife and I are moving, TDS going into the filter are not that high, I just don't know how freshwater plants/fish will react to a higher concentration of dissolved solids.
