Hello Everyone -
It has been just a little over a year since I returned to our hobby after a 20 year hiatus. Even though I am not necessarily a newbie, there has been so much to learn. I want to start keeping fishes that may be a bit more sensitive to water parameters, specifically dwarf apistos and/or discus. My tap water is not terrible - 7.0 pH with a TDS reading of 225ppm. The TDS readings in my tanks are between 330ppm and 510ppm (that one is really off - but the endlers don't seem to suffer at all). Good enough for most fresh water fish since everything I have is thriving. So, presuming I need better water for discus and apistos, which of the three water options is the best or good enough - RO, RODI or distilled?
