Sand Calculation Formula:
From: | To: |
The Sand Calculator helps aquarium enthusiasts determine the right amount of substrate needed for their fish tank. It calculates the weight of sand required based on tank dimensions and standard sand density.
The calculator uses the following formula:
Where:
Explanation: The calculation accounts for the volume of substrate needed and converts it to weight using the standard density of aquarium sand.
Details: Proper substrate depth is crucial for aquarium health - it provides biological filtration, supports plant growth, and creates a natural environment for fish.
Tips: Measure your aquarium's bottom area accurately. Typical substrate depth ranges from 2-5 cm (0.02-0.05 m) for most freshwater aquariums.
Q1: Why is sand density fixed at 1600 kg/m³?
A: This is the standard density for aquarium-grade sand, which is denser than play sand to prevent cloudiness and compaction.
Q2: How do I convert tank dimensions to area?
A: For rectangular tanks: length × width. For circular tanks: π × radius² (radius = diameter/2).
Q3: What depth is recommended for planted tanks?
A: Planted tanks typically need 5-8 cm (0.05-0.08 m) substrate to support root growth.
Q4: Should I add extra sand to account for settling?
A: It's recommended to calculate 10-15% more than the calculator suggests to account for settling and washing.
Q5: Can I use this for saltwater reef tanks?
A: Yes, but reef tanks often use aragonite sand which has slightly different density (about 1500 kg/m³).
