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.
- High wattage should be split or controller-protected on most reef systems.
Professional fit context
- Check wattage, controller, redundancy, tank size, and whether two smaller heaters are safer.
- JBJ TrueTemp G2 Titanium Heater with Controller 300W fits roughly 50-90 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
