Yeah, low pH can damage a liner.

If you didn't winterize . . . I dunno. You had a hard freeze there this winter, didn't you?

I guess what I'm thinking is, you should start up the pool, but do NOT uncover it. Then you can clean up and stabilize the water (including the pH). After that, you can put it to bed, and maybe run it a few days every month, till it's time to winterize.

Pools are sort of like old cars and old houses -- they go down FAST if someone is not using them!

(On the other hand, if you are sure you won't ever use the pool again, would it be better to look at removing it? A "no pool" is the ONLY truly maintenance free pool!
