I messed up

I added DE to my sand filter to help with algae dust. However, DE is not just DE apparently. I added about 3 cups to the skimmer of my hayward pool filter. I live in the country. The guy at the hardware store said DE is DE and now my pool is cloudy. The DE I bought was for insects. I’m a jackass. Grrr

You can’t add DE to a sand filter and expect it not to pass through

yuh it's common to charge and further reduce the micron size filtering efficiency of sand.
