temp setting on mine is way off. 73 on the heater or so is 80. Also they are glass, so they can crack or break. about 3 months on my 300w.

it is the same as a theo heater.


its a great heater, although on my theo, the temp adjustment knob was way off. i have it at "72", and it was 80 degrees...

I am having a similar issue with my All-Glass heater. I was worrying I got a dud but obviously I am not alone.

I am a little hesitant to disassemble mine because I know I will wind up snapping something off. Has anyone attempted to "recallibrate" that knob? For me 77-78 is the knob turned all the way down, so basically my lowest temp is around 77 maybe. Kind of frustrating, would like the ability to go all the way down to 71 like labeled on the heater itself.

I also had a Theo heater blow up in my refugium sump. When I installed it, I noticed that it tended to float to the surface with the hot end sticking out of the water.

Apparently, when I went on vacation, its suction cups came loose and it floated to the surface, overheated and burst. I had glass fragments sticking to the inside of my sump cabinet. Luckily, the GFI circuit cut off all power to the heater and pumps.

The problem with the Theo is that it floats. Submersible heaters should sink and stay submerged.
