Solar Cover Whoes

[macher]

In the past 2 weeks we have gone through two solar covers. I noticed one day our old one had lost all the air pockets in the bubbles [looked like a blue piece of bubble wrap that someone had popped] at the time I figured it was from high chlorine or low PH, so I bought another, waited until the chlorine lowered, made sure the PH was ok, cut it to size & toss it on the pool [its just a small 8ft diametre pool]
A day later I noticed the same thing had happened to the new cover, it had completely lost all the air pockets and was barely floating on the water surface.

I've since tapes together bits to form a 3rd blanket, it too is starting to lose its air pockets. My Chlorine & PH seem normal, pool temp is 27-29 celcius, its been very sunny lately.
I never had this problem last year, I am totally perplexed at what is causing it

Any help, suggests, or wild stabbing guesses are more than welcome

TIA,
Heather

What are your pool chemical levels, and how are you testing?

Are you leaving the cover rolled up or folded in the sun when not on the pool? That can destroy one pretty quickly.

Heather, are you putting the bubbles down and flat side up? Birds like to drink from the topside of a cover and beaks and claws can pop the bubbles - but it being the entire cover, I'd imagine that either the water chemistry or storage of the cover, when no in use, is the cause. (John, I've seen quite a few solar covers deteriorate from being folded or rolled, but it's not the entire cover and it takes a couple of months as opposed to a week or 2 , and it's deterioration from the outside (sunny side) in)
