1. What is Fish Tank Volume Calculation?

Fish tank volume calculation determines the capacity of an aquarium in litres based on its dimensions. This is essential for proper fish stocking, water treatment dosing, and equipment selection.

2. How Does the Calculator Work?

The calculator uses the standard volume formula:

Where:

• \( L \) — Length of the tank in centimeters
• \( W \) — Width of the tank in centimeters
• \( H \) — Height of the tank in centimeters

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

3. Importance of Accurate Volume Calculation

Details: Knowing your tank's exact volume is crucial for maintaining proper water chemistry, determining appropriate fish stocking levels, and calculating correct medication and treatment dosages.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank in centimeters. Enter length, width, and height values. All measurements must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Should I measure internal or external dimensions?
A: Always measure internal dimensions for accurate volume calculation, as tank walls and substrate reduce actual water capacity.

Q2: How do I account for substrate and decorations?
A: For precise water volume, subtract approximately 10-15% from the calculated volume to account for substrate, decorations, and equipment.

Q3: What's the difference between US gallons and litres?
A: 1 US gallon = 3.785 litres. Multiply litre volume by 0.264 to convert to US gallons.

Q4: Can I use this for irregularly shaped tanks?
A: This calculator is for rectangular tanks. For cylindrical tanks, use π × r² × h / 1000 formula.

Q5: Why is accurate volume important for fish keeping?
A: Proper volume calculation ensures correct filtration capacity, appropriate medication dosing, and prevents overstocking which can lead to poor water quality.
