I had my well water tested. Everything was fine, including hardness, but the pH was low (5.4). Up until a few weeks ago I had a soda ash solution feeder that corrected the problem very well. Unfortunatly, the solution feeder went up and I'm trying to decide if I should replace it in kind or try a different system. I really don't like the hastle of refilling the solution tank. I posted this same question on here a few years ago and got some good advice. At the time, I couldn't justify the cost since the other system was working fine. I can't seem to find the response to that post, though. I really appreciate any help anyone can give me.
