1. What is Fish Tank Capacity?

Fish tank capacity refers to the volume of water a tank can hold, typically measured in gallons. Knowing your tank's capacity is essential for proper fish stocking, filtration setup, and water treatment dosing.

2. How Does the Calculator Work?

The calculator uses the standard aquarium capacity formula:

Where:

• \( Length \) — Tank length in inches
• \( Width \) — Tank width in inches
• \( Height \) — Tank height in inches
• \( 231 \) — Cubic inches per gallon conversion factor

Explanation: The formula calculates the cubic volume of the tank and converts it from cubic inches to gallons.

3. Importance of Tank Capacity Calculation

Details: Accurate capacity measurement is crucial for maintaining proper fish stocking density, calculating medication doses, and selecting appropriate filtration systems.

4. Using the Calculator

Tips: Measure the inside dimensions of your tank in inches. For irregular shapes, consider dividing the tank into regular shapes and calculating each section separately.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals one US gallon, which is the standard conversion factor for aquarium measurements.

Q2: Should I include the tank's frame in measurements?
A: No, measure only the internal dimensions where water will be held. The frame doesn't contribute to water capacity.

Q3: How accurate is this calculation?
A: It's accurate for rectangular tanks. For bow-front or cylindrical tanks, specialized formulas are needed.

Q4: Does substrate affect tank capacity?
A: Yes, gravel and decorations displace water. For precise measurements, account for substrate volume.

Q5: Can I use this for saltwater reef tanks?
A: Yes, but remember that live rock and equipment will significantly reduce actual water volume.
