Please Recommend A Thermometer For A 63 Litre

[ginaekdal]

I am hoping I have gotten my mistake quota out of the way now...
 
Picked my Juwel Digital thermometer up today. Took a while to find the battery that came with it. No instructions were attached except a notice to screw the cap firmly back on afterwards.
 
Unfortunately I tried putting the battery in and forgot about the plastic thing that was stuck in place when I opened it, thinking it was a placeholder...
 
I now cannot get the battery out, the thermometer isn't working with the battery in as it is (I am guessing I also put it in the wrong way up) and quite honestly I don't want to get a Juwel one again after this.
 
Please recommend me a reasonably priced (as I already spent my thermometer budget, and have had to replace the Juwel heater as well...) one, that doesn't take a school degree to figure out how to use. Or at least one that lets you take the battery back out...
 
Apart from the thermometer and heater mess I am ready to start my fishless cycle in a day or two as I finally have my test kit, so it is not all bad.

Thanks!
 
Would you recommed having two (as in one in the tank and a cheaper one that you stick on) to have full control of the temperature? From reading I see you can get different results on the same tank depending on which you use... so would two be a better way to have control?
 
I hope to have guppies (unless my water tests later throw me off by revealing I have extremely soft water) and I understand they aren't as fragile to minor fluctuations as some fish but I'd still want to make sure I get it right!

those are the two thermometers I have on my own tank. I have the black stick on strip and the digital one too. I check that both agree with each other every day. It's belt and braces. The digital one is the most likely one to fail - mostly because the battery needs changing and so I have the 'back up' in case it starts giving me a false reading cos it's battery is failing

Thanks again!
 
I will make sure to get two. Need to save up a bit...
 
My JBL test kit did come with a thermometer so I can at least check that way until I can buy new ones, but I want one sitting in (and on) the tank once the fish go in sometime in the future.

I never trust the stick ons, I always use the old standard: 
 

 
Like $3.

I had to go digital because my Betta was attacking the glass one.

I just ordered one.

I've had them on all my tanks Eagles and they are good. I'm on my 6th tank that's had one and they've always been accurate

I use the same - and it was an absolute bargain.

I stand by my statement.  Sticking something on the outside of the glass measures the temp of the glass, not the water.  I've seen swings of as much as 5 degrees (Fahrenheit) inside the tank and outside the tank.  
 
We all know that there are potential 'microclimates' in the tank, areas that get warmer, areas that get cooler... having a thermometer that I can submerge and move around the tank (always stuck to the glass by a suction cup) allows me to see where these are.  A larger tank can have differences of a few degrees in different places around the tank, depending on your circulation.
 
 
These are also extremely useful when acclimating fish, as I can drop this in with the acclimating fish to determine when the temps are the same.  I can move them from tank to tank whenever I wish, for whatever purpose I wish, and they are dirt cheap.  Lots of advantages, and other than what Nick describes, I can't think of a single negative (aside from its potentially breakable if mistreated).
