Just wondering... on setting up new heaters
Just got 2 new eheim 200 watt heaters
I have my tank set to 78-79... one heater, the light turns on at 79, so this seems accurate. The other the light turns on at 75. Can these brand of heaters be out of wack that much? The calibrate wheel is set to the middle for both. No biggie, just wondering |
I have never had a heater that has been bang on accurate, thinking about trying a digital heater.

FYI, I set them up by setting to lowest, turning up slowly until light turns on. This will increase temp slightly, but that is OK. If I wanted to setup at lower temp to thermometer, I set to highest point, then turn slowly until light turns off. |
K, doing some googling and seeing this is quite common. People are saying the older models were better calibrated, but these are still suppose to be the best for not exploding. This true?
Maybe I should look for a controller... any affordable ones out there? |
I have glass tops and metal halide lights on my tank and haven't needed a heater (or a chiller) since I set it up last may......temp stays between 79-82
|
I'd never trust the built in thermostats. I use a ranco controller but even those are more than $100.

Had a few brand new heater that would never shut off & a few that where out by more then 5*. Thinking of trying the Oddyesea Digital or the Fluval E series digital to see if there any better.

your temperature fluctuate too much. Thats 3 degree and I am guessing between day and night. too much.
My temperature stay at 76 day and night. no fluctuation but I use a controller. 82 is quite high. Quote:
