So I backwashed and recharged My filter with DE via the near skimmer yesterday. A couple of hours later, I drained the surface water to waste for a couple of minutes to lower CYA, and then switched the multiport back to the filter setting. As soon as I did that, I saw a puff of DE entering the pool through the return jets for a few seconds. Should I be concerned? I get a little DE in the pool after every recharge, but I usually vacuum it up and the problem goes away.
