Per the awesome tips from this forum I added DE to my sand filter. But I am positive I added too much, too soon. Since the water is too cold for me to get in and feel exactly what it is on the pool floor, is it possible the excess DE flew right through my filter and came out the return, to settle on my pool floor? Also, I took my filter apart to spray out the sand as I realized, after four days of my pool not getting crystal clear, that I had a 3" layer of muddy silt on the top of my sand bed in the filter. Is it possible I didn't get most of the excess DE from the sand and it's blowing back into my pool? My filter looks to be in great shape inside, I don't feel anything is broken. Any help or insight is appreciated.
