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.
Rectangular Aquarium Volume Calculator
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.
Common Fish Tank Dimensions
While we can’t obviously cover every possible aquarium, this is a fair comprehensive list of typical tank sizes. These dimensions should be able to be a very helpful guide for designing your next setup or making changes to your existing one.
