I just moved to where the water hardness and ph level's are quite high. I have a well and have called avery city water dept. within 100-200 miles. The ph I can get down using .39c/gal safeway water through the reverse osmosis machine, but it only seems to regulate ph, not hardness. Does anyone know if this is true? I can buy a rev. osmosis machine for $200, but the ph isn't the only problem. Help!!!
