1. What is Fish Tank Volume?

The fish tank volume represents the total capacity of the aquarium in liters. Knowing the exact volume is essential for proper fish stocking, medication dosing, and equipment selection.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ Volume (L) = \frac{Length \times Width \times Height}{1000} \]

Where:

Explanation: The formula calculates the volume in cubic centimeters and converts it to liters by dividing by 1000 (since 1 liter = 1000 cm³).

3. Importance of Volume Calculation

Details: Accurate volume calculation is crucial for determining appropriate fish population, correct dosing of water treatments and medications, and selecting properly sized filtration systems.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank (excluding glass thickness) in centimeters. Enter all three dimensions to get the most accurate volume calculation.

5. Frequently Asked Questions (FAQ)

Q1: Should I include the glass thickness in measurements?
A: No, measure only the internal dimensions where water will be held. Glass thickness doesn't contribute to water volume.

Q2: How accurate is this calculation for irregularly shaped tanks?
A: This formula is for rectangular tanks only. For cylindrical tanks, use π × radius² × height. For other shapes, more complex calculations are needed.

Q3: Does substrate and decorations affect the actual water volume?
A: Yes, rocks, substrate and decorations displace water. The calculated volume is the maximum capacity before adding these elements.

Q4: Why measure in centimeters instead of inches?
A: The metric system provides easier conversion to liters (1 liter = 1000 cm³). If using inches, multiply L×W×H then divide by 61.02 to get liters.

Q5: How does volume relate to fish stocking levels?
A: As a general rule, allow about 1 liter of water per 1 cm of fish length, though this varies by species and filtration capacity.
