Biofloc tank geometry and volume calculator.
Calculate circular biofloc-tank water volume in litres, cubic metres and US gallons, including a conical-bottom approximation.
Biofloc tank geometry and volume inputs
Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry.
Method: Circular volume uses π × radius² × water depth. A conical-bottom share combines its cone volume with the remaining cylindrical volume.
Inputs used: Circular tank diameter = 4 m; Water depth = 1.2 m; Conical-bottom share of depth = 0 %
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry. Rounding and excluded real-world terms can make an external result differ.
How this biofloc tank geometry and volume calculator works
Circular volume uses π × radius² × water depth. A conical-bottom share combines its cone volume with the remaining cylindrical volume.
A worked example
A 4 m diameter tank filled to 1.2 m holds about 15,080 litres with a flat bottom.
Does this specify tank construction?
No. It calculates water volume only. Tank structural design, freeboard, plumbing and liner details require a suitable local design.
Calculations run on your device. Review your results before exporting or sharing them.
Measure the water, not the tank shell
Use the actual operating water depth, leaving the intended freeboard out of the calculation. A circular tank’s nominal diameter may differ from its inside water diameter.
A conical bottom changes usable water volume. Confirm the slope and plumbing arrangement from the tank drawing before using the result for stock or treatment quantities.
