A year or so ago I watched a video on YouTube where the person put the inners of their DE filter in a bag that trapped the DE, but allowed water to pass during the cleaning process. The bag was big enough to slip the whole filter inners into it and as he hosed it down it trapped the bad stuff so it wouldn't contaminate his yard. I have not been able to find any information via search phrases. Wondering if someone here could point me in the right direction. Thx!
