I wonder if some of the threads might be discussing two different things. What I'm talking about is the thing that looks like blue bubble wrap.
I, too, read where someone was saying it doesn't heat the water during the day and is really only for nighttime use. I'd argue that point because I know that mine will significantly warm the water if left on while the sun bakes at it.
(Which I could - if I really wanted to - confirm with temperature tests.)
I think some might be talking about a general cover for the pool.
Jenischmeni,
I think i was told by a friend not to leave it on or could've of read it on the internet. Not sure

yeah thats what I am talking about the blue bubble wrap.
What would a general cover do? protect it from debris?
thanks
