26 doesn't mean 26 gallons!

[MizTanks]

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?

i think the volume calculator you may have used was built for rectangular tanks maybe and doesnt take in the difference in the front bow panel. it probably is 26g

Why would the bow make a difference? I've entered the exact measurements. Your telling me that a slight bow in the front causes the tank to lose almost 6 gallons in volume?

6" of width added to a 90g tank adds 30g of water volume, so its very well possible?

I think your calculations are off... if anything tank manufacturers exaggerate their volumes.

Yeah definitely..... And they are the empty volume, when you put sand, rock, fish, and coral in and they start losing quickly for sure... my "14g" holds roughly 9g of water lol

And yes a slight bow will make a pretty significant difference especially in the front which is the largest panel of glass, a difference of even a half inch-inch will lose several gallons even in a tank that small.

The measurements I entered are that of the manufactures and I used this to get those gallons. http://reefnutrition.com/feed_calculator.html

They all give me 32.4g

You should use the one we have on CR

Are you accounting for the bow front?

HINT: TANK VOLUME CALCULATOR

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.

Yeah and don't be surprised if it is actually less then 26g, my "70g" is actually 67 something.... and thats outside dimensions not inside so its actually even less still
