Heres why I asked the question in the first place. Im on my 4th solar cover in 10 years which is about par. I switched to the BBB method a few years ago and had always been adding the bleach/borax by dribbling it arount the pool with the cover off. This year I started adding everythig throught the skimmer. This is the second year for this solar cover and when I go to take it off the pool it actually tears where ever I grab it, the bubbles pop at the slightest touch. This is the first time anything like this has happened. It was not like this when I put it on at the start of the season. The only thing different this year than the last is adding chemicals through the skimmer and leaving the cover on.

I'll also admitt that this year I leave the cover on when I shock as well - which may be some of the problem.

Any one know who has the best deals on solar covers? 24AG,
Thanks
John
