Hi, I'm hoping to maybe get some help figuring out why lately my pH increases almost daily. I'm attaching my measurements in pdf format. This is almost everything I track. I do use a mineral pack because I've found it seems to take some of the work off of the chlorine. I definitely have less demand for chlorine when a mineral pack is used. I was going to try to not use one this year, but I found the demand for chlorine to be much higher, so I installed one a few weeks in to the season.
My pool is 18,000 gallon gunite. I use Chlorine bleach (8.75%) and I lower the pH using muriatic acid (31.5%). I have sheers, but haven't used them lately. I also have a spa seat, but it is also off.
The list of the types of chemicals I used are on the spreadsheet. I copied the spreadsheet and eliminated columns and rows that I don't feel are important.
I hope I've given everything that may be needed. I know I'm probably forgetting something.
Thanks for any help in advance.
