For 5 years now I've had the Aqueon 26 bow front. I've always assumed that the 26 meant that it was 26 gallons. But after entering the exact measurements into a volume calculator 24.2" x 14.8" x 20.9 it actually turns out that it is 32.405 gallon.
Can anyone explain to me why then it is refereed as being a 26?
The measurements I entered are that of the manufactures and I used this to get those gallons. http://reefnutrition.com/feed_calculator.html

You need another dimension in order to properly calculate the volume of your bowfront. Right now you are entering dimensions into a calculator for a perfect rectangle, which your tank is not. CR has a calculator for bowfronts, but you will need the 4th dimension(ooooooh I'm in the 4th dimension). Measure the width, height, and depth in two places(shortest and longest). If you can get that, the calculator will do the rest.
Or you if you have a problem with our calculator (not sure why you would...maybe its the apocalypse or something)... you could calculate the volume a rectangle using the end widths, then do another volume using the middle width (as if it were that wide at the ends) and average them....if would get you pretty close. In fact, you would be getting the volume as if there was a triangle shaped front on your tank.
Either way...like Chort mentioned above, the volume you calculate isn't what is really in your tank once you add rocks and sand. My 29 gallon biocube for example has around 22 gallons in it.
