Works with Sand Filters too! Highly recommended
I have a lot of pollen in my 20x40 pool this season and could not get it gone...did some AI research and suggested using DE Filter aid even with my sand filter..works miracles! This is enough for a couple seasons too....it basically coats the sand to better filter trap the finer debris much like a DE filter works just sand instead! Never new about this amazing trick, used 3 cups ran pump and then back washed 24 hours later, pool is crystal clear now!

Great chemical brand
Use the brand all the time but wasn’t able to buy in bulk from the local store, so I was glad to be able to order here. Definitely worth the money to buy it in bulk. Makes the filter run efficiently and simple to use, just follow the proper measurements.

Great for our saltwater pool filter
We've used this DE for our saltwater pool many times and it is always done the job well. Love that I can get it in a larger quantity so I don't have to keep buying more. We do store it in a tub container just due to ease of keeping it dry than the cardboard box.
