Substrate by tank size
How much substrate for a 60 x 30 cm tank?
A starting estimate for a 60 x 30 cm tank at 5 cm substrate depth.
Estimated result
Pre-calculated from the example inputs below. Adjust them in the calculator for your own numbers.
- Substrate volume
- 9 litres
- Estimated weight
- 13.9 kg (30.6 lb)
- Bag count
- 2 x 9 kg bags
A 60 x 30 cm tank with 5 cm of substrate needs the volume, weight, and bag count shown below, using a typical gravel density. Planted layouts and slopes can need more, so treat this as an average depth.
Example inputs used
- Tank length: 60
- Tank width: 30
- Desired substrate depth: 5
- Substrate density: 1.4
- Bag size: 9
These are starting values for this example. Measure or confirm your own figures, then open them in the aquarium substrate calculator.
Assumptions and limits
- Uses a typical substrate density of 1.4 kg/L.
- Includes a 10% setup allowance and rounds bags up.
- Planted or sloped layouts may need more substrate.
Substrate depth depends on livestock, plants, and tank design. Check species-specific requirements.
