Thank you for your reply.

The pool is much better although there are some stains reappearing. The pool water was 7.8 when I refilled it and I am now maintaining it at 7.5, which seems to just stay there as long as the alkalinity is maintained at 100 not allowing for the CYA adjustment. The CYA is now 33 is this too high?

The cl is between 4 and 6 is this too high?

I did add metal out and a polyquat when I refilled.

Next time I'll try holding it 7.2 for two weeks and putting pucks in the skimmer
