Tub Sizes?

[Erratum]

Yes, but that 18 inches of height that is unneeded adds to the size of a tank. A 41qt tub has more floor space than a 10g tank. A 10g tank is usually around 20" long, 10" wide, and 12" tall. A 41qt tub adds another 10 inches in length and provide much more space.

Thanks for the clarification.

Also, thanks for the pictures Freakie_frog. Helped put this into perspective.
