Water volume is calculated using the formula of 7.48 US gallons per cubic foot of volume. Water height is taken into consideration as well so only the portion of the tank filled with water is included in the result.
Having an accurate water volume for your saltwater aquarium can help you precisely calculate how much additive you need to dose, how much salt mix to use, how much media to use, and even help determine what size powerheads and return pumps to use.
