So I've had just about every type of heater, and Ive also had every type of heater fail on me in one form or another...
To start, I keep two 300watt heaters "running" in the return section of my sump, one is run by my finnex temp controler, the other runs on its own and is set to a lower threshold.
My longest lasting, surprisingly, has been a marineland glass tube heater, but tonight i noticed the temp was 80 and the thing was still on.. looked closer and it was starting to get some condensation inside.. I pulled the top plastic section out of the water, turned it down and it turned off, but to me this thing needs to be replaced before something bad happens.
Ive tried the glass tube kind, lasted the longest
currently also have a plastic "stealth" model, it seems to be doing well but its relatively new
I had a plastic / epoxy stealth model that worked for awhile then popped the GFCI after about an hour of being plugged in.
I tried the titanium finnex element which was supposedly good, only lasted about a year and outright quit on me
so does anyone have a recommendation for a heater that isn't a piece of garbage? I cant depend on my lights to heat the tank this winter so I will need to replace the half-malfunctioning one.
