question about remora skimmers

[Todd]

While on the same thread search someone mentioned putting a piece of foam over the return (similar to the ones you would see on an aquaclear). They mentioned that they just cleaned it once a week or so. Seems like it would work although I haven't tried it yet. The Microbubbles are quite annoying, and are much more noticeable on my tank now that it is a room divider with no wall behind it.
