Can anyone recommend a reliable digital thermometer?
I got home today and my digital CoralLife thermometer was reading 87.9 degrees. I freaked out, thinking my tank was getting ultra hot. So I grabbed an "analog" mercury based thermometer and threw it in the tank. After waiting an hour or so, the mercury thermometer was reading 80 degrees, while the digital thermo was continually rising in temp, from 87.9 to 88.2, then down again, then back up again. The analog thermo remained at 80 the entire time.
I'm not sure what to trust now, digital or analog?
Can anyone give me some recommendations? Thanx
