1. What is Fish Tank Volume Calculation?

The fish tank volume calculation determines the capacity of an aquarium in gallons by measuring its length, width, and height. This is essential for proper fish stocking, filtration setup, and medication dosing.

2. How Does the Calculator Work?

The calculator uses the volume formula:

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

Where:

\( Length \) — Longest side of tank in inches
\( Width \) — Short side of tank in inches
\( Height \) — Vertical measurement in 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 tank's exact volume is crucial for determining fish stocking levels, calculating proper medication doses, and selecting appropriately sized filters and heaters.

4. Using the Calculator

Tips: Measure inside dimensions (excluding glass thickness). For irregular shapes, divide into rectangular sections and calculate separately. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals 1 US gallon. This conversion factor is standard in aquarium calculations.

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

Q3: Should I include substrate depth?
A: For fish stocking purposes, use full height. For water volume only, subtract substrate and air space.

Q4: What about metric measurements?
A: For centimeters: Volume = (L×W×H)÷1000 for liters. This calculator uses inches/gallons.

Q5: How does volume affect fish capacity?
A: General rule is 1 inch of fish per gallon, but this varies by species, filtration, and tank shape.
