the mesh socks is a great option as [MENTION=4931]reefes pieces[/MENTION] mentioned. Since it does not trap all the finer particles, what you can do is stuff it with poly filter fiber or sponge in the socks. greatly increase the polishing of the water. You can discard the poly fiber when it gets dirty. You can get a whole bag of poly fiber from Wal-mart for a few dollars. If you are in the anaheim or placentia area i can give you some.
