What this tool does
Estimate aquarium substrate mass from bed depth and material density. Use the vendor's density; particle size and porosity change mass.
How to use the Aquarium Substrate Calculator
- Enter or select tank length in in.
- Enter or select tank width in in.
- Enter or select substrate depth in in.
- Enter or select substrate density (lb/cu ft).
- Read the calculated result; change any measurement to compare alternatives.
Formula
volume=length×width×depth/1728; weight=volume×density
- length
- Tank length (in, before metric conversion)
- width
- Tank width (in, before metric conversion)
- depth
- Substrate depth (in, before metric conversion)
- density
- Substrate density (lb/cu ft)
Use the vendor's density; particle size and porosity change mass.
Worked example
For aquarium substrate calculator, the following measurements illustrate the exact method: Tank length: 48; Tank width: 18; Substrate depth: 2; Substrate density (lb/cu ft): 100.
Inputs
- Tank length48 in
- Tank width18 in
- Substrate depth2 in
- Substrate density (lb/cu ft)100
Result
- Substrate weight100 lb
- Substrate volume1 cu ft
Results explained
- Substrate weight
- Substrate weight from the formula above, expressed in lb before metric conversion. Use the vendor's density; particle size and porosity change mass.
- Substrate volume
- Substrate volume from the formula above, expressed in cuft before metric conversion. Use the vendor's density; particle size and porosity change mass.
Frequently asked questions
volume=length×width×depth/1728; weight=volume×density
No. Individual animals differ. Consult your veterinarian before changing feeding or treatment, and seek immediate veterinary care for poisoning concerns.
Use the vendor's density; particle size and porosity change mass.
Use current measured weight, actual food or product label values, and the dates or water readings requested. Check units before entering any value.
Verify if the animal is ill, pregnant, growing unusually, or on a special diet. Aquarium chemistry changes should be measured gradually and checked against product instructions.
