I remember my first "big" tank purchase. It looked like a palace in the pet store. I brought it home, filled it up, and realized I had no idea how much water was actually in there. I guessed twenty gallons. I was off by seven. That mistake led to a extremely grumpy college of neon tetras and a loud spike in ammonia. This is exactly why an Aquarium Gallon Size Calculator: Determine The perfect Sized Aquarium In Gallons is more than just a convenience. It is a leftover tool for your fish.

Calculating the aquarium calculator volume seems simple. You just produce a result the glass, right? Wrong. Well, mostly wrong. There is a specific science to finding the gallon capacity of a tank. Most people forget more or less the thickness of the glass or the space taken going on by substrate. If you want to determine the perfect sized aquarium in gallons, you have to see deeper than the label upon the box.

Fishkeeping is truly chemistry in a glass box. If the aquarium volume is inaccurate, your chemical dosing will be wrong. Medication, salt, and water conditioners are all based on gallon size. If you think you have a 55-gallon tank but you actually have a 48-gallon tank due to close decor, you are over-medicating. This can be fatal.
