1. What is Fish Tank Volume Calculation?

Fish tank volume calculation determines the water capacity of an aquarium in litres. This is essential for proper fish stocking, filtration system selection, and medication dosing in the UK aquarium hobby.

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
• 1000 — Conversion factor from cubic centimeters to litres

Explanation: The formula calculates the internal 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 determining appropriate fish stocking levels, selecting the right size filter and heater, and accurately dosing water treatments and medications.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank in centimeters. Enter length, width, and height. All values must be positive numbers. The result will be displayed in litres.

5. Frequently Asked Questions (FAQ)

Q1: Why measure internal dimensions instead of external?
A: Internal dimensions give the actual water volume, while external measurements include glass thickness and may overestimate capacity.

Q2: How does substrate affect volume calculation?
A: Gravel, sand, and decorations reduce actual water volume. For precise calculations, subtract approximately 10-15% for substrate and decor.

Q3: What's the difference between UK gallons and litres?
A: 1 UK gallon = 4.546 litres. This calculator uses litres as it's the standard metric unit in the UK aquarium trade.

Q4: Can I use this for irregularly shaped tanks?
A: This calculator is for rectangular tanks. For cylindrical tanks, use π × radius² × height / 1000. For bow-front or other shapes, consult manufacturer specifications.

Q5: Why is accurate volume important for fish health?
A: Overstocking leads to poor water quality and stress. Accurate volume ensures proper filtration capacity and prevents overcrowding.
