I think it's time to replace my heaters. they have been running 3 years. 225 gal tank, I am running 2X300w Ebo Jager (Eheim). I have been running that brand for over 40 years after having a cheep heater stay on and kill everything. Maybe 15 years ago I tried some new fangled titanium heater Marine Depot had written a glowing review of. it was very attractive not only because I'm a gearhead at heart and it was "new" but also those Ebo heaters are yuge and there's always the risk of glass breaking. I found it used a lot of electricity and didn't do a great job of heating the tank. Have any of those gotten any better or should I just stick with what works?
