The pool is nearly full (3 or 4 inches to go) and I did some testing. Ph is 7.4, cl is 0, TA is 150 and CYA is 70 - 80, probably 80 (not sure about seeing the dot). If I understand correctly, I need to aerate if possible to get the TA down. I am going to start shocking and will look at the chart to see what I need. I was hoping CYA would have dropped further. I must have drained 3/4 of the pool.

I guess I will just run high cl for now. Any suggestions?
