Safe pH levels for vinyl pools

[waterbear]

I really care more about what is right then who is right ... balanced informed decisions are for each pool owner to make. Ruining a guys vacation because he's scared to death he might get a wrinkle in his pool liner doesn't seem too balanced to me.

The point you seem to be missing is the point I made before. WHAT is causing the pH to drop and the TA to be depleted? Since we don't know the answer to that is it much safe to get the pH up BEFORE he leaves since we don't know how quickly the pH will drop. That is what is right!

Perhaps I am but that's mainly due to the fact that we have no indication that anything is driving the PH down. It might very well have been at the level for the last 4 years. We don't know because it wasn't being tested. Couple that with the notion that high CL is more damaging then Low PH I just think it should be mentioned in passing in case it's true.

Then based on what you say we should never shock a liner pool because high sanitizer will damage the liner and cause it to wrinkle by taking on water... empirical evidence notwithstanding.
(And this discussion is more suited to the china shop than in this hijack of the OP's thread.)

DurhamHouses, our advice to the OP is not changing....whether you agree with it or not is up to you. At this point, if you want to continue the debate, please do so in the China Shop so that the original poster can continue his thread here if he chooses.
