Well I stated that I had lots of questions and here they come. It seems every heater I have owned either stopped reading the correct temp or I broke it myself before it probably would have failed on its own. I always use submersible heaters. I am always looking for a better heater but they all seem to be in the same price range and all the same quality is there some out there I guess alittle more expensive that is made with quality. Or if they make a all in one system with more than one heater all tied to together. Maybe this is also something that can be controlled by the same thing my other question is about on which controler I should use? As you can tell I am in a very confused on what I should do.
