Beta calculatorGuided flow

Build the tank one decision at a time.

Move through setup, tank style, fish selection, then results. The calculator stays intentionally conservative so it can guide better decisions instead of selling a fake perfect number.

How to use it

  1. Set the tank footprint, maintenance style, and overall goal.
  2. Add the fish already in the tank so the calculator works from real stocking pressure.
  3. Use the live summary to see room left, warnings, and the safest next additions.

Beta means the logic is still growing, not that the advice is meant to be reckless.
