1. What is the Sand Bed Calculator?

The Sand Bed Calculator helps reef tank owners determine the amount of sand needed for their aquarium based on tank area and desired sand bed depth (shallow 0.025 m, deep 0.1-0.15 m).

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Area} \) — Tank base area in square meters
• \( \text{Depth} \) — Desired sand bed depth in meters
• \( 1600 \) — Density of sand (kg/m³)

Explanation: The calculation accounts for the volume of sand needed and its typical density for reef aquarium applications.

3. Importance of Sand Calculation

Details: Proper sand bed depth is crucial for biological filtration, aesthetic appeal, and creating a natural environment for marine life.

4. Using the Calculator

Tips: Enter tank area in square meters and desired sand depth in meters. Typical depths are 0.025 m for shallow beds and 0.1-0.15 m for deep sand beds.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between shallow and deep sand beds?
A: Shallow beds (2.5 cm) are easier to maintain while deep beds (10-15 cm) support anaerobic bacteria for nitrate reduction.

Q2: What type of sand should I use?
A: Use aragonite or calcium carbonate-based sands for reef tanks as they help buffer pH and provide calcium.

Q3: How do I measure my tank's area?
A: Multiply length by width (in meters) of your tank's base. For irregular shapes, approximate or divide into rectangular sections.

Q4: Why is the density set at 1600 kg/m³?
A: This is the average density for dry aragonite sand. Actual may vary slightly depending on grain size and packing.

Q5: Should I add extra sand to account for settling?
A: The calculation already accounts for packed density. No need to add extra unless you want a deeper initial bed.
