Welcome to our Hexagon Aquarium Tools. Here we can calculate three things about your hexagonal fish tank:
- Surface area
- How Many Fish your hex tank can support
Our hex calculators are available below in U.S. and metric units. For normal, rectangular tanks, follow the menu to visit the other pages on this website.
Calculate Volume of a Hexagon Tank
Enter the width of one side and the height of a hexagonal aquarium to see the volume of your hexagon aquarium
U.S. Unit Hex Volume
Metric Hex Volume
Calculate Surface Area of Hexagon Tank
Enter the width of one side, in any unit, of a hexagon aquarium to see the surface area of the aquarium.
This calculator will tell you how much surface area you have on the top of the hex aquarium, where gas exchange takes place. Whatever units you enter, the result will be in square units. For example, if you input inches, the result will give you square inches; if you put in rods, you'll get rods. If you put in astronomical units, you must have a really big tank.
Estimate Fish Capacity of Hexagon Tank
Enter the surface area of your hexagon aquarium to estimate how many inches of fish your hexagon aquarium can support.
The surface area can be used to calculate how many fish your tank can support. Generally, the tall, narrow format of a hexagonal aquarium tank will not support as many fish as a traditional wide-format rectangular tank. This is because the rate that oxygen can diffuse into the water is limited by the surface area. Check our How Many Fish? home page for the complete explanation and frequently asked questions regarding these estimates.
