Best place for an accurate temp reading?

[Dan the Fish]

hello all,
I recently bought a 10g aquarium, set it up as my research so far has informed me. I have a All-Glass aquarium heater, and its kinda quarky, it seems that the thermometer dial on the top is inacurate according to my thermometer(digital). I put it by the outflow of my filter like everyone is telling me to, but the temp its set at is 76Fdegrees and my thermometer says 79F. If I turn it up to 77F it kicks on and heats the water to about 80F-ish, I was curious if this is a common problem with those heaters or if its just a bad heater?

Common problem. Its most likely your thermometer. What kind is it? I have 2 of them, and both are in the same tank showing up to a 3* difference. IMO digital is the best way.

i have the same problem. maybe i should get a new thermometer

does th eplacement of the heater or thermometer
have anything to with the temp

its a coral life digital, i'm starting to think that it heats itself up. Do u think it would be wise to trust the temp meter on the heater?

Like the stick on, outside of the tank type?

 

[Dan the Fish]

yes

They are the worst IMO. Too often they give you a total mis read. The best, cheepest one is the ones that float in your tank.

really? where can i get a IMO? Do you know how much of a misread coralife has? and should i worry?

IMO= In my option. My stick on has a "buffer zone" of about 3*.
