First tank scare woke up to 82.5F

[Zeal]

Was messing with my heater last night no idea why I touched it, but this morning I woke up to the tempatures being 82.5F. I know for a fact the heater has been working fine it's only 2 months old but I always had an issue calibrating it..

It's one of those dang ehiem heaters... To calibrate it do I push the little red notch to the current water tempature THEN turn the blue know to match the desired tempature?

Edit: first time something like this happens so I'm worried. I reclibrated it after watching videos. I disconnected it used the red not to set the tempature at 81. Then connected it and turned the know down to 79.. hope I did this right.. the light turned on is that supposed to happen?

The problem with these heaters is they tend to stick on after being adjusted. Seems like the thermostat gets wonky.

I always calibrate mine in a bucket before putting them in a tank using a digital thermometer and then I never touch them again.

It's on right now. I have my house at 71 with the air vents hitting the tank the tempature dropped about 1.5 in an hour

If it is above the set temp, it should not be on. I would unplug it. Then plug back in. If it stays on for more than 5 minutes you may have lost the thermostat and need to replace.

Anddddd it went up .2 after being on for maybe 10min. Idkw hat to do might go buy a new one..

What size heater?

What size tank (total volume)?

Calibrated it again. Moved to red notch to 81 then turned the knob to 79... But the light is still on

I'd get a temp controller they arn't that expensive and they will save you issues in the future. Heaters are unreliable no matter what you get

40G Nuvo with the Ehiem 150w

Can I get a link for one?

That heater is awfully large for a 40g. I would get one closer to the size of your tank. The temp controller is also a great idea.

I have one that's rates for 16g as well :/

If you have a fan in the house, let it blow air across the top of the tank to cool it down.

As stated, every reefer should at least invest in a heater controller for redundancy. I don't have a reef controller on my system, but I do have a inkbird controller on my heaters. Works very well to keep this sort of thing from happening. Very cheap, around $30-$40 dollars.

I also run multiple smaller heaters, that way if one would stick on, it wouldn't be able to heat the tank all by itself. Redundancy is your friend.

I really do not like that heater. It is a pain in the neck.

I also do this in my main display!^^

I was just looking at those, what type of heater do you use?

Do those need this dumb calibration?
