I have broken a glass heater with my arm in the tank before. That is a very unpleasant experience to say the least. That was my reason for buying the finnex titanium heater, but there digital controler is junk at best. If the power shuts off it resets at 82*, so it is a chiller heater war until someone notices the chiller sure is running alot lol. The temp sensor is also very slow at reading changes. It keeps up when the temp is rising, but not when the temp drops. I like the heater it's self, just the controller is junk. Maybe another Finnex heater and just get a rancho controller instead of the Finnex.
Where is a good place to get Rancho controlers? Not having much luck finding at my normal places online.
