Just got a new Ebo Jager heater to replace my old one that is like 8 years old in my 100 gal and it says that it is not supposed to be submersed. All of the other Ebos I have, I have totally submersed without any problems, I also don't remember the directions saying that they couldn't be submersed before. Question is... I have one in my sump, should I be worried? Did they change their design or something? I noticed that they are blue now and not green and the temp control is a little bit different but except for that they seem the same.
