1. What is Aquarium Volume Calculation?

The aquarium volume calculation determines how many gallons of water your tank can hold based on its dimensions. This is essential for proper fish stocking, filtration, and maintenance.

2. How Does the Calculator Work?

The calculator uses the standard aquarium volume formula:

\[ Volume = Length \times Width \times Height \div 231 \]

Where:

Explanation: The formula calculates cubic inches first, then converts to gallons (since 1 gallon = 231 cubic inches).

3. Importance of Accurate Volume Calculation

Details: Knowing your aquarium's exact volume is crucial for proper fish stocking levels, medication dosing, filter selection, and water change calculations.

4. Using the Calculator

Tips: Measure your tank's interior dimensions in inches (excluding the frame). For bow-front or cylindrical tanks, use specialized calculators.

5. Frequently Asked Questions (FAQ)

Q1: Should I include the tank thickness in measurements?
A: No, always use interior dimensions only for accurate volume calculations.

Q2: How does substrate affect water volume?
A: Gravel and decorations displace water. For precise volume, subtract about 10-15% from calculated volume.

Q3: What's the difference between US and UK gallons?
A: US gallon = 231 cubic inches, UK gallon = 277.42 cubic inches. This calculator uses US gallons.

Q4: How often should I recalculate volume?
A: Only when you change tank dimensions or significantly alter decor/substrate.

Q5: Can I use this for irregularly shaped tanks?
A: No, this is for rectangular tanks only. Use specialized calculators for cylindrical, bow-front, or hexagonal tanks.
