Just bought a used aquarium which measures 19" x 20" x 60". The seller
said it was Oceanic Brand and held 100 gallons. My calculations came up
with less than 100 gallons, though math is not my strong point. Oceanic
no longer makes that size. Any opinions?

I get 98.7 US gallons for the outside dimensions you gave. Close enough.
Yes, that's close enough for me too. Thanks.
