Thank you, Marie. I am using more acid now to try to get my PH in line and am aerating 24/7 to help bring down the TA. I also am still trying to keep my CL at shock level, in case there still is live algae, so I might be fighting against myself, trying to do both at the same time.

I'm not familiar with the ascorbic acid treatment you mentioned. Is there a discussion about that here somewhere? I will also get a pantyhose liner in the skimmer basket tomorrow. Anything that might help is worth trying.

Frustrated, yes! Very! My husband just keeps telling me to drain it and start over, but with a vinyl liner, that's not so easy either.

It's after 11:00 pm now, so I will test again in the morning and see if I'm making progress on lowering the PH and TA. I added 12 ozs of acid twice today, so will check in the morning and will post my results.
