Donny, my apologies for not going all the way back to the beginning, but I just want to re-cap a few things okay:
- If your CYA is confirmed as still only 40, please go ahead and let the FC continue to drift down. You're about 2.5Xs the SLAM limit of 16, so we don't want any side-effects.
- You did the sand deep cleaning, did you ever add some DE to help with filtrations?
- Has your SWG been off or set to zero this whole time?
- Was the SWG off during your OCLT?
I'm going to ask you to do this ..... leave the pump running, but back off of the FC like I noted above. If you need to verify CYA one more time in bright daylight tomorrow, go ahead. But if it's still showing as 40, let the FC drop to 16. In the meantime, keep an eye on your pool. You can still sweep once a day, but for the most part I want you to back-off slightly and let the pool acclimate to its environment. Once the FC gets back to the 14 range, do another OCLT. Based on your answers above and if you pass that OCLT, then we'll discuss your situation behind the scenes with a TFP panel to see what other options might be available.
