1. What is the Aquarium Water Calculator?

The Aquarium Water Calculator estimates the actual water volume in an aquarium based on the tank's total capacity and how full it is. This is useful for water treatment dosing, fish stocking calculations, and maintenance planning.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Tank\ Volume \) — Total capacity of the aquarium (liters)
• \( Fill\ Percentage \) — How full the tank is (0-100%)

Explanation: The calculation accounts for the fact that aquariums are rarely filled to 100% capacity due to decorations, substrate, and equipment displacement.

3. Importance of Water Volume Calculation

Details: Knowing the actual water volume is crucial for accurate medication dosing, water conditioner application, and maintaining proper water parameters for fish health.

4. Using the Calculator

Tips: Enter the tank's total volume in liters and the fill percentage (typically 80-95% for most aquariums). All values must be valid (volume > 0, percentage between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: Why not just use the tank's total volume?
A: Decorations, substrate, and equipment displace water, so the actual water volume is typically 10-20% less than the tank's total capacity.

Q2: How do I estimate fill percentage?
A: For planted tanks with substrate, use 85-90%. For bare-bottom tanks, use 95%. Adjust based on your specific setup.

Q3: Does this account for water evaporation?
A: No, this calculates the volume when filled to your specified percentage. For evaporation, you would need to measure the actual water level decrease.

Q4: Can I use gallons instead of liters?
A: The calculator uses liters, but you can convert gallons to liters (1 gallon ≈ 3.785 liters) before entering the value.

Q5: How precise does this need to be for water treatments?
A: Most treatments are safe with slight overestimation, but being within 10% of actual volume is recommended for medications.
