Hi! My first thermometer is off by like 50 degrees, went and got two more. They usually agree. Could be placement in the tank? One is a suction cup in tank and the other is a stand up one on the bottom. Question is...should I get an outside digital one that sticks on? How do you read those? What price range? How acurate are they for the water temp? Thanks! Clueless hellann...  ;D |

I don't recommend that you get the outside digital one. They are just measuring the temp that is on the outside of the glass. Ones that you submerse in the water will give you a more accurate reading.

I have the little glass ones that suction to the side of the tank. I usually try to place them on the opposite end of the tank from the heater, in a place where I can read it easily

Clueless hellann... ;D Since Bettas (and most fish) can adapt to a variety of temperatures, the most important thing is consistency of temperature, not accuracy to the nearest 10th. We have some of the glass one's that stick inside the tank with suction cups and I have one with a metal frame that hangs on the edge, by penn plax. They all agree and they were all around the $3 range. I use the metal one for my water changes to make sure the temps match. Our biggest problem has not been accuracy, but OLD eyes. This may not be a problem for all the young'ns on this site, but for me, those little numbers and lines have gotten really little! My husband just bought a digital (battery operated) thermometer for that reason. It is really nice and seems to be really sensitve with readings to the 10ths (not needed). The readout suctions to the outside of the tank and a probe hangs in the tank and measures the water temp. They are big, though. He uses it on our 75 gallon tank. Bottom line is that most are pretty accurate, and you really don't have to spend much unless you want to. It sounds to me like yours are working for what you need them to do. |

Hi! Thanks for the replies. :-)
I have thrown away the defective thermometer.
I noticed when buying the new ones, that the ones in the store were sometimes off. They should all read the same. So, I would recommend actually reading a few of them before purchase. Compare them.
I also noticed that on some of the cheap-o type, the thermometer was sometimes positioned higher or lower on the card inside, therefore giving a "false" reading. If I held a couple together, I could see that they were reading the same, just that the card guide wasn't accurately placed.
Just a heads up.
