Ok have to ask...what is a gallon cap?

[brewercm]

Gallon capacity.

Basically the volume calculation is what he was looking for.

The other way to calulate it is: cubic feet/7.47 = gal.

1 ft. X 1 ft. X 1 ft. = 7.47 gal.

My tanks is 72 X 22.5 X 18 = 16.875 cu. ft. = 126 gal. The 1 gal. difference is due to the thichness of the glass. A 1-2 gal. difference is common if you use outside measurements. Obviously, the thicker the glass, the more difference.
