Aquarium Volume Calculator

There are various reasons you might want or need to use an aquarium volume calculator:

  • Determine the true volume of a custom aquarium 
  • Find the true volume of an off-the-shelf fish tank
  • Decide the necessary dimensions of a custom tank install
  • Help in selecting an appropriate equipment such as:
    • Return Pumps
    • Sump Size
    • Reactor Flow
    • Skimmer Size
    • etc.

Cylindrical Aquarium Volume Calculator


				

Uniquely shaped aquariums will require a bit of thinking to sort out. A bow front, for instance, can be calculated by measuring the rectangular section first. Next measure the bow front section as if it were rectangular and divide by two. 

Be sure to check out our article that explains everything you need to start a saltwater aquarium.
