i have a digital thermometer on my 350ltr with the sensor half way down pointing to the middle of the tank, but also have a glass thermometer stuck to the glass. Now the thing is my digital one keeps reading 26oC an above its now reading ajust above 28oC, but my glass one is reading 25oC - 26oC? bearing in mind i haven't got my heater plugged in as didn't see the point of having it plugged in when its that temp already? My other tank in the same room always reads a steady 25oC with heater on? Now i'm confused is my digital one over reading an glass one right or vice versa? if u follow all that? please any help??
