Substrate Volume Formula:
| From: | To: |
The Aquarium Substrate Calculator estimates the volume of substrate material needed for UK aquarium tanks. It helps aquarists determine the correct amount of gravel, sand, or other substrate materials required for their setup.
The calculator uses the substrate volume formula:
Where:
Explanation: The formula calculates the volume in cubic centimetres and converts to litres by dividing by 1000, providing an accurate estimate of substrate requirements.
Details: Proper substrate calculation ensures optimal aquarium health, provides adequate surface area for beneficial bacteria, supports plant growth, and creates a natural environment for aquatic life.
Tips: Enter tank length and width in centimetres, and desired substrate depth. All values must be positive numbers. Consider adding 10-15% extra for optimal coverage and settling.
Q1: Why calculate substrate volume accurately?
A: Accurate calculation prevents waste, ensures proper biological filtration, and maintains water chemistry stability in your aquarium.
Q2: What depth is recommended for different setups?
A: Planted tanks: 5-8cm, Fish-only tanks: 2-5cm, Deep sand beds: 10-15cm depending on species requirements.
Q3: Does substrate type affect the calculation?
A: The volume calculation remains the same, but different substrates may compact differently, so consider buying slightly more than calculated.
Q4: Can I use this for irregularly shaped tanks?
A: For irregular shapes, calculate the average dimensions or divide into regular sections and sum the volumes.
Q5: How often should substrate be replaced?
A: Most substrates last 2-5 years. Replace when it becomes compacted, discolored, or water parameters become difficult to maintain.
