As I suspected our pool CYA is super high. The black dot never disappeared. Prior owner shocked weekly and used chlorine pucks. I removed the puck did no shocks and waited for new test kit.
The pool tested 0 chlorine, 7.8 pH, and off the charts CYA. I did not complete other tests because it was a little overwhelming but will try again.
Am I right to understand we need to drain some water, and add liquid chlorine? Pool math says 10 gallons and drain some water. Do I do both? Not sure how to drain the pool, but I’m sure the internet will help with that…I hope.
