1. What is Aquarium Volume Calculation?

The aquarium volume calculation determines the total water capacity in gallons based on the tank's dimensions. This is essential for proper fish stocking, filtration setup, and water treatment dosing.

2. How Does the Calculator Work?

The calculator uses the standard aquarium volume formula:

Where:

• \( Length \) — Longest side of aquarium (inches)
• \( Width \) — Shortest side of aquarium (inches)
• \( Height \) — Vertical measurement (inches)
• \( 231 \) — Cubic inches per gallon conversion factor

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

3. Importance of Volume Calculation

Details: Knowing your aquarium's exact volume is crucial for proper fish stocking levels, accurate medication dosing, and selecting appropriately sized equipment like filters and heaters.

4. Using the Calculator

Tips: Measure inside dimensions of the aquarium (excluding glass thickness). For irregular shapes, measure average dimensions. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Should I include decorations/substrate in volume calculation?
A: For fish stocking purposes, subtract about 10-15% for decorations and substrate to get actual water volume.

Q2: How accurate is this calculation?
A: Very accurate for rectangular tanks. For bow-front or cylindrical tanks, specialized formulas are needed.

Q3: Why 231 cubic inches per gallon?
A: This is the standard US liquid gallon measurement (3.78541 liters = 231 cubic inches exactly).

Q4: How does water level affect volume?
A: Measure to the actual water line, not the top of the tank, as most aquariums aren't filled to the brim.

Q5: Can this be used for saltwater reef tanks?
A: Yes, but remember saltwater systems often have sumps - calculate main display and sump separately then add.
