Hygger titanium heaters with temp control have been solid for me. More than any other heater ive used. I have two running in tandem. My tanks temp has never drifted +/- 1degree.![]()
This heater looks good but I notice it recommends a 100w heater in a 10 -26 gallon tank! I think these recommendations from manufacturers and other people are part of the problem. There is no way you need a 100w heater in a 10 gallon tank! I have a system that's 50 gallons and it has a single 75 watt heater in it that runs exactly 8% of the time (I know because I checked it with an energy monitor). I'm actually thinking about getting a 50w heater or maybe even a 25w. Every heater is going to fail eventually and most likely get stuck to "on". Your heater needs to be sized so that when that happens it doesn't boil your fish before you notice! There is a difference between heating cold water to 78 degrees and simply maintaining your tank at 78 degrees. Maintaining a consistent temperature requires much less energy than heating it up initially.
