I gave it a good 5 minute backwash and 2 minute rinse today and then took the head off to inspect the sand. It appears that there is some type of sediment in the sand that's not backwashing out. It's really hard to describe (hence the pictures) but when I take some out it felt like wet paper or wet cotton balls ... Not sure if this is from a product I've used or what, but like I said, it doesn't backwash out. Any ideas?
