Hi,

I have a DE filter and we noticed some DE around the pool. After vac. it up, it comes back. Dh took the filter apart and inspected the DE grids and they do not look torn or worn. We had a similiar problem last year and it was due to a hole in one of the DE grids and we replaced it. The filter itself is less than 5 years old. We did notice that when we opened the tank, all the DE was on the bottom and a little DE on the grids. Is this suppose to be like this??

Thanks for any info.

Karen
