Just completed a self-water well test. Everything checked out great except it showed Ph levels of 10 or greater. We have a house filter system w/ two 20 gallon drums we maintain with the filter system--one drum has a bleach/water and soda ash mix and the other a water and polymer mix. Any suggestions? I thing I read somewhere that the soda ash has something to do with the ph levels? Any info would be great. thanks.
