How big can I go while keeping the same light?

ReefGeek,

You're right. I forgot to mention the styrofoam under the tank. I like to get mine from Rona (blue as opposed to HomeDepot's pink).

OCDP,

If you did the stand in just 2 by 4s & stained it, that would save you money until you can buy all the trim & doors, etc. Those could be added later on to the front & sides with no problem, leaving the back open.

If you AC500, you can just take off the top & add a hanging shop light or clip on desk light (around here, the Phillips Daylight CFS bulbs from HomeDepot are popular).
