Liner Pool Care

[aylad]

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.

Here are some pictures I took today, you can see the gray/blackish stains. What do you guys think they are?

Test readings today were,

Chlorine levels below 1ppm
pH 7.3
TA 210
CH 185
CYA over 100

I cannot get accurate readings on my CYA tests due to my test kit and high water temps here in Louisiana. Lamotte says that my CYA tests will be inaccurate with water temps over 85 degrees.

I am going to have to start using Cal-Hypo tabs from now on in this pool, I need to get that TA lowered and by adding Stabilized tabs it keeps making my pH levels decrease due to their low pH level.

I really need to drain the pool some and put in fresh water, the CYA level is way too high as well.

You will be using trichlor for a very long time if you are trying to use it to lower the TA. Just use muriatic acid since it takes a LOT more acid to lower TA than pH by any appreciable amount.

Depending on the TA of the fill water you use this could lower your TA also (if it is lower than the TA of the water in the pool.)
