I recall the morning I brought house what I thought was a 55-gallon tank. I bought it off a guy on a urge on lane forum. He swore it was a standard size. I got it home, filled it up, and bonus my favorite African Cichlids. A week later, I was dosing some water conditioner. I followed the 55-gallon instructions. Within hours, my fish were gasping at the surface. Why? Because that "55-gallon" tank actually unaided held 48 gallons of water once you factored in the glass thickness and the trim. Using a trustworthy Aquarium Calculator Gallon would have saved me a lot of draw attention to and a few near-dead fish.
