How to Use This Calculator
- Enter the number of fish you plan to keep alive in the live well during your trip.
- Input the average fish weight in lbs to calculate total biomass load.
- Enter the surface water temperature in °F — warm water holds less dissolved oxygen and increases stress.
- Set the tournament or fishing duration in hours to account for water quality degradation over time.
- Read Recommended Capacity in gallons — choose a live well at or above this size.
- Set your aerator to at least the Aeration Rate (GPH) shown, and exchange water at the Water Change Interval (minutes).
