Jeroen Posted March 5, 2006 Report Share Posted March 5, 2006 I am setting up my first aquarium and have trouble finding a decent thermometer. I wonder if anyone knows a accurate thermometer. Looking around almost all thermometers read at 0.1 decimals and +/- 1C. I dont find this that accurate especially if you try to keep your tank within a 3C band. But it gets a lot worse. I bought a 2nd hand aquarium with an analogue hang on thermometer. This read reasonble but to my feeling about 1C low and changes too slow. I have another 2nd aquarium and this had a digital thermometer that to my feeling reads good but only shows whole degrees C. So I bought a digital thermometer (the aquaminder). This is terribl, it reads about 3C high and changes too quick. So I bought another digital one from trademe. This one fluctuates about 0.3C but about the right temperature for the first few days, now it reads also about 3C high. I checked this with a thermometer from work which I could check with a calibrated thermometer In total I have now 4 thermoters in my aquarium all reading different and a spread of almost 4C (betwenn 25.5 and 29.5). Anyone out there that knows a good relaible thermometer? Jeroen Quote Link to comment Share on other sites More sharing options...

Alan Posted March 5, 2006 Report Share Posted March 5, 2006 I go for the normal thermeter you'd find in any LFS, but the trick is to compare all of them. You'll have highs, lows, and a group between. Choose one of these and forget about being so pedantic about the temperature that you want for your fish. I check mine against a dairy thermometer that are normally VERY accurate and meke the mental adjustments necessary for any difference in the bought one. Another good thermometer is the home brew ones, bigger, more expensive, but if you check the temp of a group of them you'll get one to suit your needs. Easy to find to if you put it down somewhere due to it's size. Alan 104 Quote Link to comment Share on other sites More sharing options...
Sharkey Posted March 5, 2006 Report Share Posted March 5, 2006 I bought a new flashy digital one a couple of years ago it had all the different settings also the time etc .. A year down the track it was giving me wrong temp readings Which caused all sorts of problems( Good lesson there double check any odd readings ) now I have one of the cheap mercury ones in the sump I think it was $3 and it reads fine. IMO that's all you need. Save the money for all the other stuff you will need to spend it on. Skimmers Pumps etc etc Quote Link to comment Share on other sites More sharing options...
