Worked amazingly well at cleaning out my sand filter. Wish there were instructions on how to do it, I had to get instructions from another company's website to properly do it. But it worked really well. Couldn't get my pool filtering at all, this cleaned it out and got it working perfectly again.

Works as advertised
