Aquarium Water Volume Formula:
| From: | To: |
The Aquarium Water Volume Calculator helps reef aquarium enthusiasts accurately determine the actual water volume in their tanks, accounting for substrate displacement and leaving space at the top. This is essential for proper dosing of additives, medications, and maintaining water quality.
The calculator uses the following formula:
Where:
Explanation: The 95% fill factor accounts for substrate displacement and leaving some space at the top of the aquarium, providing a more realistic estimate of actual water volume.
Details: Accurate water volume calculation is crucial for proper dosing of water conditioners, medications, fertilizers, and maintaining stable water parameters in reef aquariums. Over or under-dosing can harm delicate marine life.
Tips: Measure the internal dimensions of your aquarium in centimeters. Enter length, width, and height. The calculator will provide the estimated water volume in liters, accounting for substrate displacement.
Q1: Why use 95% fill factor instead of 100%?
A: The 95% factor accounts for substrate (sand/gravel) displacement and leaving air space at the top for gas exchange and to prevent overflow.
Q2: Should I measure internal or external dimensions?
A: Always measure internal dimensions for accurate volume calculation, as glass thickness reduces internal space.
Q3: How does rock work affect water volume?
A: Live rock and decorations further reduce water volume. For heavily decorated tanks, consider using 90% fill factor for more accuracy.
Q4: Can I use this for freshwater aquariums?
A: Yes, this calculator works for both freshwater and saltwater aquariums, though reef systems often require more precise volume calculations.
Q5: What if my aquarium has irregular shape?
A: For irregular shapes, break it down into regular geometric sections and calculate each separately, then sum the volumes.
