Update and pretty much all good news. Have been checking the water pretty much twice daily to monitor cl usage. Had a close call on the 1 36 or 48 hour period that I didn't check cl as it dropped to about 4 and looked like algae was getting ready to go two days before a pool event for one of my kids. Hopped up the cl and managed to get us through the night. Cleaned up and has been good since. Had a good weekend in the pool over the 4th.

Am now in the process of draining. down about 13 inches. I have a hose running onto a lounger to minimize mixing of water and my skimmers are turned off to pull water from the bottom drain.

Have been "bumping" the filter as well figure we can start it new at the same time. Goal is to leave about 4-6 inches in the shallow end and then turn the pump off for the refill. Going camping next weekend so this will give us some time to stabilize the chemicals and cl demand before everyone wants to hop in again.

BTW, have probably gone through 20 1.42 gal jugs of cl keeping it in the 8-12 ppm range. (remember my CYA is so high I can't really measure it).

Thanks for the help. Going to test my fill water shortly.

Cheers

Brian
