Aquarium Heater Calculator V1.11

This calculator determines the minimum size heater required for a given tank size and difference between the desired water temperature and the room temperature.

It implements the equations found in the Aquarium Thermodynamics chapter of Aquatic Systems Engineering by P.R. Escobal.

This program is for information purposes only, the author assumes no responsibility if you make fish ice cubes or fish stew with your tank by following its advice.
