the general tank size (sorry was in a hurry measuring so not perfect) is

36 x 18.5 x 14.25

The sites with the tank sizes say that the 40 breeder is this

36 3/16 x 18 1/4 x 16 15/16

the obvious difference there is on the Height.

Anyhow so I went to the tank calculator on the FL site, and I come up with this.

Aquarium Size is 41.08 US Gallons

Rounding down, just for kicks, to 36x18x14 gives this result:

Aquarium Size is 39.27 US Gallons

So is the tank size list inaccurate or what? I've noticed that it seems to be a cut n paste on various sites when googling, and all the data seems to be the same. Am I doing something wrong?
