1. What is Aquarium Capacity Calculation?

The aquarium capacity calculation determines the volume of water an aquarium can hold based on its dimensions. This is essential for proper fish stocking, filtration setup, and water treatment in the UK aquarium hobby.

2. How Does the Calculator Work?

The calculator uses the standard volume formula:

\[ Capacity (L) = L \times W \times H / 1000 \]

Where:

Explanation: The formula calculates volume in cubic centimeters and converts to liters by dividing by 1000 (since 1 liter = 1000 cm³).

3. Importance of Aquarium Capacity

Details: Knowing your aquarium's capacity is crucial for determining appropriate fish stocking levels, calculating correct medication dosages, and selecting properly sized filtration equipment according to UK aquarium standards.

4. Using the Calculator

Tips: Measure the internal dimensions of your aquarium in centimeters. Enter length, width, and height. All values must be positive numbers. Remember to account for substrate and decorations that reduce actual water volume.

5. Frequently Asked Questions (FAQ)

Q1: Why measure internal dimensions instead of external?
A: Internal dimensions give the actual water volume, while external measurements include glass thickness and may overestimate capacity.

Q2: How does substrate affect capacity?
A: Gravel and sand displace water, typically reducing capacity by 10-20% depending on substrate depth and type.

Q3: What's the difference between UK and US gallons?
A: 1 UK gallon = 4.546 liters, while 1 US gallon = 3.785 liters. This calculator uses liters for universal understanding.

Q4: Should I fill the aquarium to the very top?
A: No, leave 2-3 cm from the top to prevent water spillage and allow for surface agitation.

Q5: How accurate is this calculation for curved tanks?
A: This formula works best for rectangular aquariums. For bowed or cylindrical tanks, specialized formulas are needed for accurate volume calculation.
