Looking to get my chemicals correct to close the pool. The local company wants me to buy ~$500 in chemicals. I put (6) gallons of 7.5 % bleach in last night, and it's a bit clearer. I also added 3/4 gallon of maurtic acid. Any advice is welcome. The hard one is the alkalinity doesn't seem to be coming down, even though the pH dropped 0.2. See attached numbers.
