1. What is Aquarium Volume Calculation?

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

2. How Does the Calculator Work?

The calculator uses the standard aquarium volume formula:

\[ Gallons = \frac{Length \times Width \times Height}{231} \]

Where:

Explanation: The formula calculates cubic inches first, then converts to gallons using the standard conversion factor.

3. Importance of Volume Calculation

Details: Knowing your aquarium's 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 (excluding glass thickness). For irregular shapes, measure average dimensions. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why 231 cubic inches per gallon?
A: This is the standard US gallon volume conversion (1 gallon = 231 cubic inches).

Q2: How do I measure a bow-front aquarium?
A: For bow-front tanks, measure width at the widest point and use 0.8 as a correction factor.

Q3: Does this account for substrate and decorations?
A: No, this calculates total volume. Actual water volume will be less when accounting for displacement.

Q4: How accurate is this calculation?
A: Very accurate for rectangular tanks. For other shapes, specialized formulas may be needed.

Q5: Can I use centimeters instead of inches?
A: Yes, but you'll need to use a different conversion factor (1 gallon = 3785.41 cm³).
