as we all know all standard manufacture aquariums they claim the gallons that was listed.. did anyone check if it's correct or not?? give it an example a standard 180 gal is 72 x 24 x 24h... that's 180 gallons, but when you measure it correctly that's ONLY the plastic Frame of the tank... Now if you measure the inside dimension of the tank where the water is stored it's really 71.25 x 23.25 x 23.5h that makes 169gallons.. that's only if you fill the tank to the top plastic bracing... so i'm little confused here.. now if i do the same for my 300 gal tank it's really even smaller...
