Very good product
Used this on my very dirty Sta-Rite cartridge filter and it did a great job cleaning it up. Soaked it over night and it did a fantastic job.

I followed the directions for a sand filter, but found no improvement in filter workload (PSI) or increase in water clarity.

DE Grids Squeaky Clean
I'm ashamed to admit that I had not cleaned my DE grids in 10 years. They were covered in brownish stains and a greasy coating of.... Ugghh, I don't want to know what! So I mixed up a batch of the Filter Perfect and soaked the grids for 24 hours. When I rinsed them off, they still had the brown stains but the greasy coating on them was gone. I was pleased enough with the results that I will use this product on other parts of the filter that need cleaning.

I used it on my filter after the season this year-the filter was brown. This cleaner made it white again!!
