Alright, I have been through 3 Visitherm (stray current), a Marineland (glass cracked), and now a Digital Finnex Titanium (stuck on). What do you recommend me to do. It seems like any heater has seriously potential for failure, it just takes time. The titanium heater laster well over a year before it's failure. I need a heater that will last that will be placed fully submersible horizontal. I want to avoid the high cost of a Ranco Controller, but is that my only option to avoid the inevitable failure? Any highly recommend heaters for my application (submersible and can sit horizontal)?
