Well, one of our Clownfish met his doom in the return pump chamber of our Biocube.  The pump intake sucked him in and, well you can figure it out.  I read this is a common problem among Biocube owners, particularly with Clowns jumping into the chambers.  Does anyone have a tried and true solution to prevent this, besides getting a different tank and fish(;p)?  Someone on the nano-reef forum said they used a piece of gutter guard from Lowe's to cover the pump chamber.  I'm not crazy about the idea of egg cartons which seems to be a common recommendation.
