I replaced the sand sacks that came with the pool with plastic jugs full of sand. But I cant get rid of the sand that keeps settling on the bottom. My readings are great and my pool is sparkling thanks to following BBB. So those little whisps of sand stick out like a sore thumb and are driving me nuts. I vacuum it up and as soon as I have to backwash it's back. I rinse after backwashing. But as soon as I switch back to filter I see it coming out of the jet. What can I do? Should I backwash and rinse longer? I feel like I'm emptying the pool. Obviously I'm doing something wrong. I know one of your brilliant minds and experience can help me. Thank you!
