Its sad that the cheapest least expensive piece of equipment can actually cause the most damage.

No mater what they all suck that's why I committed and excepted the fact that once every single year ALL heaters get replaced no matter what. Thirty dollars isn't worth the thousands I have invested.

In addition the next best thing is to have it set a touch high and have it connected to a controller. So that the internal thermostat doesn't get welded on, which is why they all fail on and not off. I also use two undersized heaters one in sump one in DT so if one fails the other can keep up the job until I can replace it.

I've always believed in the reliability of Stealth heaters but have come to accept the fact that they suck too. I actually have one 3 months old in the grow out tank that started to shock me the other day.......off to the mixing barrel it goes!
