Cobalt Neo-Therm 200W Submersible Heater fit check
Cobalt Neo-Therm 200W Submersible Heater is a 200W thin-profile heater. ReefCrafter's 2.5-5 watts-per-gallon band puts it at roughly 40-80 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.
