Their (11.5" x 24") hexagon aquarium calculator seems to be incorrect, saying 41.2 gallons, while everyone else says 35.7...

Just go to their forum and let them know . The calculator is probably not their's anyway .

have you tried reaching out on social media ?

Most aquariums are not true to their volume. A quick google search will tell you that it's usually under what the specified gallons/liters amounts are. In my case, I have a 30 Breeder and it's actually more than 30 gallons filled.

The gallon difference seems like it is too large to be an external vs internal dimensions error right? I think the glass would have to be quite thick for that to add up to 5 gallons.

Breaking it up geometrically into two triangles and a rectangle, calculating/adding up the areas and then multiplying by 24", I get 7662 cubic inches or 33.16 US gallons.
