I have some of those socks for the skimmer. The little bugs I have float, so vacuuming won't bother them. They seem to be more abundant during the day. Probably seeking relief from 110 degrees in direct sun, and my pump runs at night. Skim them off at night, and their relatives show up the next day. The little buggars are beating me down. LOL Just gotta use the fine-mesh leaf net several times a day if we are in the pool.

Thanks folks,
jeff
