So i have a stock tank that is outdoors, uncovered with all the natural elements. I have a 100 gallon stock tank and need a heater. I bought one that i was going to use for an indoor habitat, it was a stealth heater. So i used it in the stock tank outdoors and it stopped working. So i read the instructions and it said indoor use only. So since i used it wrong it obviously wont be covered under the warranty. What would be a good choice for a heater for this stock tank?
I was thinking a pond heater but all i can find is bond de-icers which i assume are different and would not work for what i need.
Any help would be appreciated.
