Frankly I was shocked when I took the cover off my pool this last spring after using this kit to close it in the fall. My pool was crystal clear and CLEAN!! So I bought the kit again, and will use it every year from now on. Great kit that works well.

There are so many dimples to punch. I used a hammer and big nail. It took a lot of pounding because they’re all over. Other than that, easy to use.

The pool was a mess, we finally got it cleaned and balanced, but it still was a bit cloudy and not clear. However, we went ahead and put this closing kit into it and hoped for the best. The pool is very clear and clean and perfect even though the weather is too cold to use it. We live in the south, so we do not cover it for the winter. Very pleased with this product and the price.

I have been using this kit for years now and it works every time. It has everything we need to close the pool and in the spring the water is clean and the opening is easy. I will continue using it.
