Liner Pool Care

[Jasheon]

I have a few questions about a liner pool care, I took over a liner pool around in September of last year. Everything was perfectly fine but once November came around the customer told me that she was going to take care of the pool in the winter and was going to contact me in May once it warmed up and they were ready to swim.

So the winter went by and they called me in the middle of May. I go over there and I noticed that the pool has developed A LOT of wrinkles at the bottom of it. The pool is only a year and 4 months old. The pool did not have wrinkles back in Sept. My guess is that the pH level got way too low and developed wrinkles. Is there a way that a company could drain the pool and fix the wrinkles? Also I have noticed lately that at the bottom of the pool there are these dark spots, it's like dark clouds but they are underneath the liner itself. I tried brushing/vacuuming/netting etc to see if i could feel it, I cannot. Any idea what in the world these black spots are? I am just taking a shot in the dark here, but maybe it's water that has settled underneath the liner?

Also, I do not have access to liquid chlorine where I live, and bleach just won't cut it. Should I be adding stabilized Chlorine Tablets or Cal-Hypo ones?


Thanks!

Without current water testing numbers, we can't tell you whether to add stabilized chlorine or cal hypo. If you'll test with drop-based kit, and post numbers, we can better advise you. You're right, there is no liquid chlorine in Louisiana, but I use bleach very successfully in my pool (I'm near Shreveport). I just run my stabilizer up higher than most to compensate for the climate difference.

Odds are good that the pH got too low and caused the wrinkles, but they are also good that the ground water is so high in our state that pressure from the water, especially if it's pooling under the liner, has caused them. Again, testing numbers will help us there. Also, if there's water pooling under the liner, I'm sure the black spots are black algae or possibly mold. NOthing you can really do if it's under the liner, but bleaching the heck out of it (in a controlled fashion) will help if it's on top of the liner.

As far as draining a pool, especially with our ground water, it usually will make the liner unuseable again. If it's not above ground, the water table will likely "float" the shell, if the company doesn't know what it's doing.

As I haven't seen you yet, welcome to the forum!

Aylad has you covered with the possibilities - is the liner puckered in small areas or more like a spider's web in the shallow end, leading towards the deep?

I've been doing IG liner pools almost exclusively for the past 10 seasons and don't mind sharing the tips and tricks I've picked up

It's GREAT to see other pool dudes come here to try to perfect their mastery of pools!

It an above ground pool, I will get the chemical readings next week and post them.

You're not waiting a week in Louisiana without chlorine though, right??

No of course not, I went over there yesterday.
