Thermometer inaccuracies.... - Aquarium Advice

Lonewolfblue · 10-31-2005, 04:40 PM

I just noticed that my temp strip on the glass is very inaccurate. I just got a digital thermometer with a probe that goes in the tank. The one on the glass says 78 and the probe says 74.2. Big difference there. I think I'll trust the probe, and bump my temp slowly up to 78.

The one on the glass says digital, but is way off. It's the kind that doesn't use glue to stick and you can move it anywhere on the tank. So I'll just remove it and get rid of it. Wonder if it would be more accurate in the tank? Not sure it will stick that way, lol.

wow...I'd use a 3rd thermometer and see what that says...that's a big difference

Not all stick-ons are perfect. I got the digital off of Amazon.com. It's called Water Thermometer. I can have it display the tank temp or the air temp in the room, and have high and low alarm settings.

I quit using my stick on for that very reason, almost always a 4 degree difference in the temp at least. I have a digital for the 125 and a suction cup type for the others.

I put my old thermometer back in the tank, sits on the bottom. It's maybe a degree different than the digital, if at all. So the digital is correct, and the stick-on is way off.

I had a stick on first too when I started out with aquariums. Like yours it was way off too
