Compatibility math

Safe wattage band

2.5 <= total watts / display gallons <= 5.0

Example: 100W is usually a planning fit for roughly 20-40 gallons before room-temperature and redundancy choices.

ReefCrafter checks both the low-wattage failure and the oversized stuck-on failure.

Risk notes

  • A single oversized heater can cook livestock faster than a beginner notices the problem.
