Just to explain why I asked you to test TA and pH:

I hadn’t seen a pH test result on your thread for a while. After seeing your pool the other day, I got to thinking that MAYBE your pH had risen. There was a potential for the “raging waves” (as your kids call the jet action on the pool surface) to have aerated the water. Lots of splashing does it too

Aeration raises your pH. Chlorine loses effectiveness at high or low pH levels. IF your pH had risen due to aeration (and chlorine additions), then getting pH back in range would be VERY important. Does that make sense?
