stupidly, I added DE tonthe skimmer without the pump running. So when looked up, a cloud was forming in the pools deep end. I ran the filter for 48 hours and ran the robot several times. The water is clear but I still cant get an answer on whether it is ok to swim. The DE never settled on the bottom in a visible amount. The robot basket had a tablespoon of sandy silica in it which seemed kinda sharp and in the filter basket. That made me a little worried about swimming. Thoughts?
