1. What is the Fish Tank Gravel Calculator?

The Fish Tank Gravel Calculator helps aquarium enthusiasts determine the amount of gravel needed for their fish tank based on the tank dimensions and gravel density.

2. How Does the Calculator Work?

The calculator uses the gravel weight formula:

Where:

• \( L \) — Length of the tank (meters)
• \( W \) — Width of the tank (meters)
• \( D \) — Depth of gravel layer (meters)
• \( density \) — Density of gravel (kg/m³)

Explanation: The formula calculates the volume of gravel needed (L × W × D) and then multiplies by the density to get the total weight.

3. Importance of Gravel Calculation

Details: Proper gravel calculation ensures you purchase the right amount for your aquarium setup, preventing waste or shortage. It also helps estimate the weight your tank will need to support.

4. Using the Calculator

Tips: Measure your tank dimensions accurately in meters. Typical gravel density is about 1500 kg/m³, but check your specific product. Depth should be your desired gravel layer thickness (usually 5-8 cm).

5. Frequently Asked Questions (FAQ)

Q1: What's the typical gravel density?
A: Most aquarium gravel has a density between 1400-1600 kg/m³. The calculator defaults to 1500 kg/m³.

Q2: How deep should my gravel layer be?
A: For most freshwater aquariums, 5-8 cm (0.05-0.08 m) is recommended. Planted tanks may need deeper substrate.

Q3: Should I account for tank decorations?
A: This calculator gives the total amount needed. You may need slightly less if you have large decorations occupying floor space.

Q4: Can I use this for sand?
A: Yes, but sand has a different density (typically 1600-2000 kg/m³). Adjust the density value accordingly.

Q5: How do I convert kg to pounds?
A: Multiply kg by 2.205 to get pounds. For example, 10 kg × 2.205 = 22.05 lbs.
