Works like a charm!

I'm new to cleaning filters. (I'm an old pro at backwashing a sand filter.) This cleaner has made the process much easier and the filters much cleaner. I would recommend it to a friend.

Crystal Clear Pool

I was getting ready to be away for 5-6 weeks. I do my own pool care and wanted to boost up the chemistry a little bit. I used this and came home to a clear pool with all chemicals in normal range. I am pleased with product.
