I inherited a 55 gallon. The measurements are so absurd it's just going to have to remain lidless. is there a good planted tank light that I would be able to safely mount on this thing? It's a 48 by 12 tank without a center brace. But this outside rim makes it 48.5 by 13. The rim is between an inch and 1.5 inches. But the inside rim starts at .5 inches and is 46 5/6 by 11 1/6. Yeah, effing evil. Help!?
