How to calculate aquarium biomass density
This calculator finds aquarium biomass density by dividing total fish biomass by tank volume — an important stocking metric for maintaining water quality and fish health.
How the calculation works
Biomass density = Fish biomass ÷ Tank volume.
Example
200 grams of fish biomass in a 40-liter tank: Biomass density = 200 ÷ 40 = 5 grams per liter.
Frequently asked questions

Pro Tips for Aquarium Biomass Density
- Recommended maximum biomass density varies significantly by fish species, filtration capacity, and water change frequency — check guidance specific to your setup.
- Biomass density is generally a more accurate stocking metric than a simple 'inches of fish per gallon' rule of thumb, since it accounts for actual mass rather than just length.
Common Aquarium Biomass Density Mistakes to Avoid
- Using a generic stocking guideline across very different fish species, when bioload (waste production relative to size) varies significantly between species.
