Good question, Terry, as we were discussing this last night with the neighbor. Sorry to hijack your post, we have the same exact filter as Terry, and this is the third season of using it. We have been backwashing since Saturday and have noticed some sand loss. Wewere wondering if the sand becomes less effective over time (years) of filtering.
