I don't know if panty hose will work, tights might work better as the mesh is tighter ( you would also need a good elastic).
A "skimmer sock" looks like panty-hose but the mesh is much tighter. You put it inside your skimmer's basket with the eleastic part wraped over the lip of the basket.
works awesome for pollen, bugs and some types of algae.

you could also buy a pool devil as well to do additonal skimming...
same idea, it's a large sock that that collects debris & attaches to your return outlet
