Which heater do you use?

I had the same issue with my neo-therm heater. The heater was submerged for an hour then I plugged it in. It cracked and smoke was coming from the crack in the heater.

Was this a 200w model? Either way, I would contact Cobalt Aquatics and ask them what they can do for you.
 
get a ranco controller to controller the heaters,i wouldn't trust the apex controller or the onboard controller on the heater,they're alway off by 2 to 4 degree :eek1:,That a Huge different .I'm using jaeger currently.good luck bud

2nd that I also use ranco controller and a Rena smart heater.
 
Cobalt neo therm 200 watt on my my 2 34 gallon Red Sea. I like them. Oversized but I like my room cold at night when I sleep no problems..

Just food for thought but me personally I would not use that heater at all. Failures are popping up more and more one leading to whole tank catastrophe and people displaced from their home due to the toxic smelling smoke. I'd run from that
 
FYI, There were problems with some of the 200 watt models cracking and leaking black goo into the aquarium. Cobalt said it was a bad batch that was manufactured in early 2013 and that the problem has been fixed. I think the water was getting in where the cord enters the top of the heater. There is a big thread about it on RC. Almost all that cracked were 200 watt, although there were some 150 watt mentioned in the thread.
