I am having a new vinyl liner installed in the next 2 weeks. This will be my second liner in the last 6 years. The precious one developed wrinkles along the the wall of the shallow end.The wrinkles were so bad last year that the liner would not stay in the track in the shallow end. In addition the liner and white steps have a brownish stain. The pool is an 18'x36' Foxx. As near as I can tell it has a 25000 gal capacity
I have had trouble maintaining a ph above 6.8 for the last 3 years. I would add ph+ according to the pool store recommendation. The ph would come up but withinin a week or two it would be back down. We had several storms last season which didn't help. I have had a problem keeping chlorine levels above 1.0. The alkalinity drops to 60 or 70 several times a season. I have been using Leslies 3" Tri-chlor pucks in a Hayward Chlorine feeder for the last 6 years. Last year I went through almost (4) 35lb buckets of tabs.
I found this site last fall. I have been reading different posts all winter. I am thinking the CYA was too high which caused my ph problem. The low ph caused the liner to wrinkle. I have the the Leslies DPD test kit that I use to test the water. Several times a season I would take a sample to the pool store just to confirm my test results. I failed to test the cya often enough last year. The pool store only tested it once and early in the season.
I also have had an algae bloom 2 or 3 times each year. I have always used an algae preventer on a weekly basis. Low to no chlorine at times probably cause the algae to take over. I had changed the sand in the 300# filter 2 years ago. Just to start out fresh I removed the sand last weekend.
My pool store is having their annual 25% off sale starting today. I am getting 12 cases of chlorine. 5 bottles of algae preventer. New sand and some 3" tablets. I am only going to use the tabs until the cya gets up to 30 and will then switch to liguid chlorine. I am ordering a Taylor K2006 test kit from Swimming Pool Supply today. Once the pool test results are stable I want to try the BBB method. Can anyone think of anything else I should pick up at the sale? Am I thinking right on the possible cause of the liner damage? I realize without accurate test results it is pretty much a lot of guesswork. Thanks in advance for any suggestions.
