just curious, prefer not to go the RO approach and enjoy just filling my reservoir with a garden hose. my water is about a pH of 7.5 and TDS of 130ppm. I've been using a hose carbon filter and have respectfully gotten tds down to around 80-100 ppm. Just curious if I'm the only one using tap water for reservoir water?
