1. What is Fish Tank Volume Calculation?

The fish tank volume calculation determines the water capacity of an aquarium in litres. This is essential for proper fish stocking, filtration setup, and water treatment dosing.

2. How Does the Calculator Work?

The calculator uses the standard volume formula:

Where:

• \( Length \) — Longest side of tank in centimeters
• \( Width \) — Short side of tank in centimeters
• \( Height \) — Vertical measurement in centimeters
• \( 0.001 \) — Conversion factor from cm³ to litres

Explanation: The formula calculates the internal volume in cubic centimeters then converts to litres (1 litre = 1000 cm³).

3. Importance of Proper Tank Sizing

Details: Accurate volume calculation ensures appropriate fish stocking levels, proper filtration capacity, and correct medication dosing for aquatic life.

4. Using the Calculator

Tips: Measure internal dimensions in centimeters for accuracy. For bowed or irregular tanks, use average measurements or specialized calculators.

5. Frequently Asked Questions (FAQ)

Q1: Should I include substrate depth in height?
A: No, measure only the water column height. Subtract about 2-3cm from total height to account for substrate and air space.

Q2: How does shape affect volume calculation?
A: This calculator is for rectangular tanks. Cylindrical tanks require πr²h formula, while bow-front tanks need more complex calculations.

Q3: Why calculate in litres rather than gallons?
A: The UK uses metric measurements for aquarium products and fish stocking guidelines. 1 UK gallon = 4.546 litres.

Q4: How accurate should measurements be?
A: For small tanks (<50L), measure to nearest 0.5cm. For larger tanks, 1cm precision is usually sufficient.

Q5: Does tank material affect volume?
A: Glass thickness reduces internal volume slightly (1-2% for standard tanks), but this is usually negligible for stocking purposes.
