Sicce Scuba Preset 300W Submersible Heater fit check
Sicce Scuba Preset 300W Submersible Heater is a 300W preset shatter-resistant glass submersible. ReefCrafter's 2.5-5 watts-per-gallon band puts it at roughly 60-120 gallons of display water, before room temperature and redundancy choices. At this wattage a controller or a split two-heater setup limits the damage of a stuck-on failure.
Sicce Scuba Preset 300W Submersible Heater: fits roughly 65-90 gallon systems. Specs, compatibility math, sizing risks, and alternatives before you buy.
Who it is for

Compatibility math
Safe wattage band
Example: 300W is usually a planning fit for roughly 60-120 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.
- 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.
- Sicce Scuba Preset 300W Submersible Heater fits roughly 65-90 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
