Aquarium Volume Formula:
From: | To: |
Aquarium water volume calculation determines the actual water capacity of an aquarium tank, accounting for substrate and decorations that displace water. Accurate volume measurement is essential for proper fish stocking, medication dosing, and filter selection.
The calculator uses the aquarium volume formula:
Where:
Explanation: The formula calculates the internal volume and applies a 10% reduction for substrate displacement when selected.
Details: Knowing exact water volume is crucial for maintaining healthy aquatic environments, proper fish stocking levels, accurate medication dosing, and selecting appropriately sized filtration systems.
Tips: Measure internal dimensions in inches, select whether you have substrate (gravel/sand), and choose your preferred output unit (gallons or liters). All measurements must be positive values.
Q1: Why subtract 10% for substrate?
A: Substrate (gravel, sand) displaces water volume. The 0.9 factor accounts for typical substrate depth and water displacement.
Q2: Should I measure internal or external dimensions?
A: Always measure internal dimensions for accurate water volume calculation, as glass thickness reduces internal space.
Q3: What about decorations and equipment?
A: This calculator provides base volume. Additional displacement from rocks, driftwood, and equipment should be considered separately.
Q4: How accurate is this calculation?
A: Very accurate for rectangular tanks. For bow-front or irregular shapes, consider using water displacement measurement.
Q5: Why is water volume important for fish keeping?
A: Proper stocking (1 inch of fish per gallon rule), accurate medication dosing, and filter capacity all depend on knowing exact water volume.
