When I started up my 5 gal
nano, I had a (I think Therma-Temp) alcohol thermometer, which always seemed to read high in the past (when it was in my 5gal)
For my 44 gal
I got a Coralife electric thermometer, but I think it's reading low...
I also got one of the stick-on strip thermometers to put on my 5 gal
, which now sticks on the side of my 44 gal
Currently, the chiller is set to keep the water at 79 degrees, the alcohol thermometer is reading 79 degrees, the Coralife thermometer is reading 75.5 (And 188.8 if I jiggle the wire near the base), and the stick-on strip thermometer is reading 78
When I first got the Coralife and the alcohol thermometer, I calibrated them both by sticking them in ice water, and both read 32F
I'm guessing the temperature is around 78-79 (2 outta 3 ain't bad)
Anyone have good or bad experiences with any of these thermometers? Could a low battery cause the misinformation on the Coralife?
