Can a water filter be used to change pH of water?
I know that I need to lower the pH of the water I use for my indoor herb garden (basil, thyme, oregano), and I've gotten suggestions to use products such as PH Down. But I wonder if it's possible to install a water filter on my tap that can lower the pH. Does anyone know anything about doing this? Brita filters, reverse osmosis, etc? Thanks for any thoughts.
