Note: When you buy a 55 gallon tank, it isn’t actually 55 gallons. Often tanks are smaller in actual water volume than what they are said to have. For accuracy measuresments should be made from the inside of the tank. Measuring the outside of the tank will give a slightly less accurate measurement.
