Sand Weight Formula:
| From: | To: |
The Aquarium Sand Calculator helps determine how much sand you need for your aquarium in UK pounds. It calculates the weight based on your tank dimensions and the density of the sand you're using.
The calculator uses the following formula:
Where:
Explanation: The formula calculates the volume of sand needed and then converts it to weight using the sand's density, finally converting from kilograms to UK pounds.
Details: Calculating the correct amount of sand is important for proper aquarium setup. Too little sand won't provide adequate substrate for plants or beneficial bacteria, while too much can create dead spots and waste money.
Tips: Measure your aquarium dimensions accurately in meters. The default density of 1600 kg/m³ works for most aquarium sands, but check your specific sand's density if known. Depth should be your desired sand bed depth (typically 2-5 cm for most setups).
Q1: What's the average density for aquarium sand?
A: Most aquarium sands have a density between 1500-1700 kg/m³, with 1600 kg/m³ being a good average value.
Q2: How deep should my sand bed be?
A: For most aquariums, 2-5 cm (0.02-0.05 m) is sufficient. Planted tanks may need 5-8 cm for root growth.
Q3: Should I buy extra sand?
A: It's recommended to buy about 10-15% more than calculated to account for settling and any errors in measurement.
Q4: Does sand type affect the calculation?
A: Yes, different sand types have different densities. Fine sand is typically less dense than coarse sand.
Q5: Can I use this for other substrates?
A: This calculator works for any granular substrate if you know its density. Gravel typically has a higher density (1800-2000 kg/m³).
