I have measured my pool twice and used the pool calculator to determine the gallons. I have come up with 21,400 gallons. I follow the instructions on the pool calculator to a T, but I keep having wild swings in my chemistry after putting in the prescribed amounts. For example, yesterday I needed to lower my pH from 7.8 to 7.2. With a TA of 210, the pool calculator said to add 105 oz of muriatic acid-which I did. Then I ended up with a pH at 6.8 (or possibly lower because 6.8 is the lowest reading I have). Then I had to add borax to raise the pH back to 7.2 so I could do my AA treatment.
This sort of thing has happened repeatedly, and I am blowing through products like crazy. What am I doing wrong???
Thanks for taking a look-Stephani
