Filter socks

[lastlight]

My return pipe just extends down into my sump and is submerged. I don't have room really to make a nice tray with filter sock holes for the water to fall into. Is it ok to just rubber-band the sock onto the end of a pipe and have the whole sock submerged? Or will this be a bad idea? I actually want to use them and don't mind buying a bunch so I can swap'em every day.
