If all else fails, I'll just buy some plexi sheets and drill a bunch of holes in it.
Look for eggcrate in the lighting section of your local Lowes, HomeDepot, or hardware store. It's used as a diffuser panel on 2 x 4 foot overhead light fixtures.
, DON'T use plexi, unless you are covering a very small area. The heat from the aquarium causes plexi to warp over time. Another option, if the area is small, is needlepoint mesh. You can get this at any craft store. HTH
