Since I have just dumped 1/2 the water in our pool and refilled I will not be buying a new liner this year! All of the puckering kind of smoothed out and I have a few wrinkles which I can live with. New liner is on the list for next season. I will be getting the readings on the pool since the refilll in about 1 hour. Will post them asap.
I have ordered the testing kit you recommended. Will be glad when it arrives, probably Monday.
Thank you for helping me!!
