Here are my tests using tf100. I am installing a swg and started doing a partial drain in my pool a week ago (20%). I did a cya extended test and still had around 180. This time remove about 80% and here are my results
Ph 7.2 (was 8.0 last night before acid)
Ta 150 (was 180 last night)
I have to aerate my pool to get the oh up before I can add more acid to adress the ta
Also dang auto fill got stuck on last night so I have to remove couple inches today the cya was at 60 yesterday
Any other thoughts?
