I've read the reviews on this type of thermometer..I have one, but I don't use it. I use lifeguard I believe it's called. Most of the people that use them say they check w/ a glass thermometer every once in a while b/c they are very inaccurate. Hope you had no losses!

Well I think you would tell the difference from 78 and 88 by sticking your hand in there...?

Doubt this will work but maybe change the degrees from Fahrenheit to Celsius? Maybe the coralife is messed up and will read something else. Convert the C to F online and see what you get...don't know if this will help. The heater doesn't have a way to tell temp does it?

Oh well then if both read the same thing I would think it's 78. What's the temp in your house?

You cranked it up all the way? I know for my aqueon heater in my 10 FW even on the lowest setting it would be like 80 or 82 even though the house was about 72 so I just took it out. Aha! Maybe this will work. Get some cold tap water...or RO/DI if you really want and put both thermometers in. Maybe the accuracy will be revealed.
