We need to SLAM, we allowed our FC to go too low after company was using our pool. Our OCLT showed a loss of 2 overnight this morning. CYA is currently 50, PH is 7.2. The chart shows CYA 60, not recommended, with an SWG. Should I raise the CYA before starting the SLAM?

Thanks for the quick answers, off to get fresh chlorine, we used the last we had yesterday.

Edit: looking at the SLAM chart again for non-SWG and SWG pools, this makes total sense! Thanks again!
