I remember the day I brought home what I thought was a 55-gallon tank. I bought it off a guy upon a back up alley forum. He swore it was a all right size. I got it home, filled it up, and extra 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 by yourself held 48 gallons of water past you factored in the glass thickness and the trim. Using a well-behaved Aquarium Calculator Gallon would have saved me a lot of bring out and a few near-dead fish.

Calculating your tank size isnt just nearly bragging rights. It is a safety issue. If you dont know your fish tank volume calculator results, you are basically guessing every period you go to chemicals, salt, or medication. Guessing is bad. Science is good. Lets dive into how you can stop guessing and start living thing accurate.

Most people think they can just see at a tank and know the size. "Oh, that looks similar to a 20-gallon long." Well, is it? Or is it a custom acrylic job thats two inches shorter? Water is incredibly heavy. Each gallon of freshwater weighs approximately 8.34 pounds. If you miscalculate by five gallons, that is more than 40 pounds of extra weight your floor or stand wasn't expecting.
