I won't have access to rodi water for at least a week..can I use Tap water in a pinch? Its a biocube 29 and I change 5 gallon at a time..I have a ZOA frag, tree and two mushrooms in there..so will tap water due for this weeks water change?
I personally have AWFUL tap water. When my Ro/DI went down, and it still is down btw, I switched to distilled water that I buy from the store. Has been much better on my system, and might be a viable option if you are in a similar situation.
