What caused my wrinkle?

[razor]

So far doing well. Grandson was over last night swimming so I didn't close the cover until 11 PM. I added Chlorine yesterday morning and ran pump on slow speed. Open up cover at seven this morning and added chlorine. I remember when I was slamming in April I closed the cover one day when it was storming and I could see the air pockets between the water and the cover. I paid attention to when I open the cover this morning and it was like taking the lid off a jar it's definitely holds gas in. The pool builder told me when he installed the cover to make sure I opened it so they could gas off. Will let you know how this is going after a few days. Thanks for your help.

Well here is what I know now. It is not the cover causing the problem or the heater. I had the wrinkle come back as I increased the chlorine dose to 9.
Thinking liner has a problem or has been damaged by chemicals. Really don't know what caused it but dosing FC to 6 all is well. Don't know what would happen if I needed to slam again.

Here is a picture of the wrinkle. It spreads to other parts of the pool if I keep FC dose at 9.

I guess the damage is done. I see a new liner in my future. Hope that it is a while before it is needed.

Very interesting though I'm very sorry for the problem. Literally tens of thousands of folks doing similar without an issue. I can't figure what's going on. That liner still looks brand new!

I just skimmed this thread.....it sounds like you have groundwater getting behind the liner and floating it. That's about the only way a liner can "wrinkle" and then straighten back out.

Will get a liner guy here to check it out.

Have called a pool guy to get and see my issue. It has got worse in the last 24 hours. It is on three sides of the pool in several places. Waiting to hear back from pool guy.

Ok the pool guy I called is backed up installing liners since May was so cold to install any. So he hasn't got here yet. I have been using pool and adding chorine using the TFP method. All the wrinkles are gone now as they came and left several times. I was wanting to try and get the water from behind the liner but could not find anywhere how to get the liner loose. The liner has a keeper that keeps it in. Never figured out where the water came from either. Oh well they are gone now.
