I moved into current house with Inground pool 11 years ago. The last owner had great heavy duty tarp that lasted me about 6 years. I don’t know how long he had used it for but when I got it, it was used at least once. After I retired that great tarp, I bought two new ones so far. Each of them only lasting two years. Technically, only one year because collected water on top of tarp seep through tarp the second year. Does anybody know where I can get a great heavy duty tarp?
