I just started my own pool company and I've noticed that each of the handful of pools I've gone to for estimates has had high levels of CYA 80-90 and the previous pool guy is using liquid chlorine as well as chlorine tablets to keep the levels up. I'm in South Florida and was planning to only use liquid chlorine to keep CYA in check but I'm worried that the chlorine will burn off within a week due to the rain and UV this time of year.

How are these pool guys using tablets every week? Are they draining the pools periodically? It's my understanding that draining pools in South Florida is a liability.

Also I've noticed that all the pools I've tested have low levels of calcium hardness, very low alkalinity and thus very low LSI/CSI. Don't pool companies keep these levels in check? I was under the impression that an LSI under -0.3 is corrosive for pool equipment.

I replaced my Pixel 10's rear camera glass because it was cracked but noticed that ever since it cracked it had this smudge. It's only at 1x zoom. How can I fix it?? Thank you for any help!!
