1. What is Aquarium Volume Calculation?

Aquarium volume calculation determines the total water capacity of an aquarium in US gallons. This is essential for proper fish stocking, medication dosing, and filter selection.

2. How Does the Calculator Work?

The calculator uses the standard aquarium volume formula:

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

Where:

\( Length \) — Aquarium length in inches
\( Width \) — Aquarium width in inches
\( Height \) — Aquarium height in inches
\( 231 \) — Conversion factor (cubic inches to US gallons)

Explanation: The formula calculates the cubic volume in inches and converts it to US gallons using the standard conversion factor of 231 cubic inches per gallon.

3. Importance of Accurate Volume Measurement

Details: Knowing your aquarium's exact volume is crucial for maintaining proper water chemistry, stocking appropriate fish populations, and accurately dosing medications and water treatments.

4. Using the Calculator

Tips: Measure the internal dimensions of your aquarium (excluding glass thickness) in inches. Enter all three dimensions for accurate volume calculation. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals exactly 1 US gallon, which is the standard conversion used in imperial measurements.

Q2: Should I include substrate and decorations in my calculations?
A: No, calculate the total internal volume. Substrate and decorations displace water, so actual water volume will be less than calculated.

Q3: How accurate is this calculation for irregularly shaped aquariums?
A: This formula is designed for rectangular aquariums. For bow-front, cylindrical, or other irregular shapes, specialized formulas are needed.

Q4: What's the difference between US gallons and imperial gallons?
A: US gallons (231 cubic inches) are smaller than imperial gallons (277.42 cubic inches). This calculator uses US gallons.

Q5: How much should I reduce the volume for substrate and decorations?
A: Typically reduce calculated volume by 10-20% depending on the amount of substrate and decorations used.
