Volume Formula:
| From: | To: |
Fish tank volume refers to the total water capacity of an aquarium, measured in liters. Accurate volume calculation is essential for proper stocking, filtration selection, and water treatment dosing.
The calculator uses the standard volume formula:
Where:
Explanation: This formula calculates the internal volume of a rectangular aquarium, converting from cubic centimeters to liters for practical aquarium measurements.
Details: Knowing your tank's exact volume is crucial for determining appropriate fish stocking levels, selecting the right size filter, calculating accurate medication doses, and maintaining proper water chemistry.
Tips: Measure the internal dimensions of your tank (excluding glass thickness) in centimeters. Enter all three dimensions as positive numbers. The calculator will provide the volume in liters.
Q1: Why measure internal dimensions only?
A: Internal dimensions give the actual water volume. Including glass thickness overestimates the available water space for fish and plants.
Q2: How does volume affect fish stocking?
A: Larger volumes allow for more fish and better water stability. A general rule is 1 cm of fish per liter, but this varies by species and filtration.
Q3: Should I fill the tank to the very top?
A: No, leave 2-5 cm from the top to prevent fish from jumping out and to allow for proper gas exchange at the water surface.
Q4: How does substrate affect volume?
A: Gravel, sand, and decorations reduce actual water volume. For precise calculations, subtract approximately 10-15% for substrate and decor.
Q5: Can this calculator be used for irregular shaped tanks?
A: This calculator is designed for rectangular tanks. For cylindrical, bow-front, or custom shapes, specialized formulas are needed.
