I use ROIf you do pH your water for soil... best to bubble-out the chlorine for 24 hours, rather than adding pH down. Do more with less.
Reverse Osmosis water eliminates the chloro and everything else from water and gives you a clean slate to build your nutrient solution.
Chlorine will evaporate if water is let sit but chloromine, fluoride are going to be still in there with God knows what else.
Like I said, tap is fine for hobby growing but if you are seeking the dankest of dank, use high quality inputs.
