Just curious.......what is everyone paying for a gallon of muratic acid. My pool store of all places seems to be the cheapest but they are still going up and now at $4.60 per gallon (18.00 per case of 4). Is Muratic acid the least expensive way to bring down PH. I have always needed to add MA every few days to bring my PH down, I never seem to have to raise it. Lowe's is $6.00 per gallon, hardware store is over 6, etc. I just want to make sure that everyone uses MA for ph reduction.
