Guys/Gals,

I'm thinking of building a rimless frag tank say, 36 x 20 x 12 (maybe shorter) should be just over 40 gallons...

I've built smaller tanks before, always with bracing and what not - but it was a long time ago - and now i find myself wondernig what the rule is on stands/surfaces for rimless tanks...

do you go whole hog like acrylic and put a piece of foam under them or go you only support the edges... my brain has forgotten... stupid brain...
