I have somewhat the same problem...there is a lot of "dust" in the air by my pool...trees collect it, wind blows, dust in the water! I don't see the dust/dirt returning in the return jet, though. I switched to the zeolite 2 years ago, and that really didn't help me. I'm going to try the skimmer sock this year to see if when I vacuum the dirt will be caught in it!

Good luck.
