Hey guys just making sure I don't have a new dud heater. Got a brand new Eheim Jager thermostat heater 300w for my 125. Followed the instructions, set the temp to 85, and plugged it in horizontally as it won't fit vertically.

The light has yet to come on. My 200w is struggling to keep the tank at 80, so I'm wondering if it's just needing to take its time? I saw the heat coming off of it immediately after plugging it in, but after 30 minutes now, still no light or no heat it looks like. Patience or help?
 
Have you calibrated it? What was the tank temp when it looked like it was on and heating?
 
Well, it's working but now I calibrated to 80 which is what my thermometer constantly shows, and it turns off now before going to 85 which is where I'm setting it. I can't turn the red calibration up past 80.

Temperature looks like it has went up 1 or 2 degrees.

My 200w heater is still constantly on. Why are these things so complicated lol
 
Yeah it's a discus tank. It just kicked back on so I'll monitor it and check in the morning before I leave for work.
 
I have not gotten a new Jager in awhile, but I think they say to give it a few days of adjusting and calibrating in some cases. Make sure you have a good thermometer too.
 
Up to 82 now and it shut off again so it's at least working.

My 200w on the other side still has not shut off. I have it set on 86. Is this gonna run our electric bill up like crazy or do they not affect it that much? We had 4 tanks running previously. Only have this 125 and a 20g now so lm hoping it isnt a big deal. I'll be getting a thermometer controller after Christmas.
 
So it's holding at 82 overnight. 200w heater is still constantly on. It doesn't seem like I can calibrate this thing to the temp it needs to be calibrated to. It only goes to 80 degrees and can't go up past that.

Kinda frustrating to say the least. My aquatop heater is much easier to operate. Should I turn the 200w off and try to Calibrate from there, or just turn the heater up to 88 or 90 and let it try to hear to 85 from there?

Maybe after 24 hours it'll be closer to being right.
 
I'm thinking of getting a catalina aquarium heater, 3 or 500 watt. Comes with a controller already also
