Cleaned my filters really good.

This cleaner did absolutely nothing for my pool filter. I followed the directions exactly, soaked the cartridge overnight, and the filter still looked dirty and clogged. The liquid itself seems watered down, not concentrated at all. On top of that, it has a strong chemical smell that lingers even after rinsing. Definitely not a 6-month supply. Save your money and buy something that actually works.

Not a six month supply. Didn’t work very well.

I’ve always been told to soak my filter in muriatic acid to clean it. I avoided cleaning the filter because disposing of a 20 gallon garbage can full of a muriatic acid mix is hard to figure out. It kills the grass permanently, and it’s not the safest solution to handle. I’m so glad I gave this product a try. It dropped my priming pressure by 10, my jet output is stronger, and disposing of the product was easy. If you have one large filter, you need two bottles. Other than that, the directions are clear and the product is excellent.
