Coralife Digital Thermometer problems

Has anyone else had problems with Coralife Digital Thermometer problems? If not are you really using it like the instructions say to do so. I believe they say to turn the unit off when you are not using it, does that mean when your not looking at it? Or just when it is not in a tank or terrarium and in a drawer.

I have found that you can't turn them off. When you push the power button it thinks the temp changed for some reason. If you push and hold the same thing and it usually doesn't turn off. It seems as if you have to have a stop watch and press and hold for a specific number of seconds. I bought two of them from the same store, but I purchased the second one months later and the store goes threw inventory very fast.(Thatpetplace PA) One of them that started to read very off temp and then the battery expired, this was probably near the end of the battery life. The other I have left on for the longest time. This past week I was at a fellow reefers and noticed he had one. I asked him how he liked it and he said he thought it was great. I asked if he had ever turned it off and he said that he hadn't; when we tried it was the same thing. The unit decided it was a different temp all of a sudden and would not turn off.

I contacted ESU's customer support and they asked me if I would remove the battery and wait a while then try again. I had done it before, but this time left the battery out for an hour and tried.... didn't change anything. I wrote them back the next day and now three months later have not heard from them. VERY disappointing as I had high respect for the company and have thought in the past that there products were pretty solid and worked well. They also seemed like a well organized company, but with poor tech support... Errrr...

So now what do I do? I need a reliable way to watch the temp in my tank. I've used the floating glass thermometers for ever and have tons of them, but I'm starting to trust them less and less as I begin to keep more fragile things. Should I just continue to use the coralife and just leave it one? Battery still lasts a long time. I plan to get a temp probe and connect it to my PC,(probably using Dr. DAQ) but the funds aren't there for it right now.

Buy a contoller to control your thermometers. Most controllers if you buy a decent one have very good thermostats in them and are accurate to within 1 degree.

You mean to control my heaters? I don't want to spend money on a controller of any type. I'm either going to try yet another one of these small digital thermometers that are under $10 or probes that can attach to my pc.
 
If you do turn it off when you arnt looking at it then it works fine and turns on and off normaly. If you leave it on the whole time then it dosnt want to turn off after a while.
 
Hum... If coralife had a person in RC maybe this could help them figure out how to fix it. So vanmo92 you'd suggest getting another then? They first started doing this when I left them at my brothers house and had my Dad check on the tanks 3 times a week, he may have forgot. Or I could have.
 
I have 4 of them and just let them on all the time.

Once 1 of mine went to all 8's and wouldnt tell the temp for weeks.
No matter what I did I couldnt get it to work. All of a sudden it started working normal again on it's own weird.

I would just keep it on.

Mine never turns off, I have tried it. I think the temp reading is off too. :( Both my glass temp. reader and the ReefKeeper 2 says the exact same thing. I was thinking the sump is cooler then the display tank BUT that can not be because the water in the sump eventually reaches the display tank. Its next to impossible for 2 tanks connected to each other to be diff. temps... think about it. I'm subscribed.
 
Depends on how dramatically different. They can be different. I have two tanks that are connected with different temps, but the transfer between them is very slow to nothing. Something else that can come into play is light warming the other objects in the tank. But yeah they can't be too different.

I think I am going to get the Dr. DAQ and probably Dr. Aquarium. I may pick up another coralife thermometer and try turning it off every time, but if it doesn't work one time then I will just leave it on. The one I have now is currently working on a freshwater tank fine, just never turns off.
 
as I had high respect for the company and have thought in the past that there products were pretty solid and worked well.

heh, i've always thought the exact opposite, except for the thermometer which i like alot. i have 2 and leave them on all the time, no problems. sometimes get weird reading when i move it too close to my stack of electronic ballasts.
 
I have 2 of them and both of them read different temps... they both read different temps from my aquacontroller as well, one of them doesn't stay on anymore and is always waking out (turning on and off since I dropped it in the water once) the other one works alright but part of the LCD stopped working for no apparent reason.

IMO they are exactly what they are... a $5 thermometer. They might be alright for a FO or to give you an idea that your temp isn't really hot or cold (within about 2 degrees) but if you want accuracy (within a tenth) they are junk.
