I used the blue styrofoam instead of pink on my BB tank.

Tony you could always put some sign board between the styro and the underside of the glass. That stuff comes in almost any color. Just a thought.

Tank's too heavy to roll it onto the side and paint it, otherwise I'd consider that. I'd have to ask for 3 or 4 sets of hands to help me with getting it onto its side, and I'm thinking I'd rather save that favour to ask for instead getting the tank onto the stand when the time comes..

Maybe sign board would work .. that's an option I was sorta thinking about too.
