Yesterday evening we added DE to our sand filter to see if it would help filter out the very fine pollen we get from the cottonwood trees in our area. We first did a backwash, and after reading our users manual for our Hayward Sand Filter, we also put it on rinse for a minute after backwashing, which we never did. We just went by what the previous homeowner told us she did, which was only backwash. What we have noticed since doing these 2 things is that our return jets seem to be shooting out the water further. Not sure if it is because of the rinse that we did or because of adding DE in our sand filter..............any thoughts?
