Recently purchased this heater for one of my 10 gallon tanks and I paced it completley underwater where as with other heaters like this one I submerged them just pastthe minimal water line. I'm pretty sure its safe becuase if it shorted out I would prob have blown a breaker by now. I just want to make sure before I place my hand in there
its a marineland visi-therm heater exactly like this one.
