Broken heater -> Tank Crash in Progress

[Midway]

I had a heater it went hay wired on me once too. It took a few corals out but the system recovered pretty good. I'm with Kien on this one, Have the heaters controlled by controllers...priceless big piece of mind. If heater gets stuck, controller shut it off at the temp you set yourself when setup heater on the controller. If the heater/s for some odd reason fail to turn on, there's go an email to your email account saying the low temp you set up yourself too has been reached so you can react right away. I know controllers are not cheap but they paid them selves big time saving you money and big time head aches in the future.
