BeginnerFishKeeper Posted November 20, 2021 Share Posted November 20, 2021 I recently set up my eheim heater for my quarantine tank and followed the directions carefully (when I say I annotated the instruction manual I’m not kidding). I set the temp to about 78 using the blue dial then waited around 2 hours. I came back to check the temp using a digital thermometer and a glass thermometer and they both measured around 83°. I unplugged the heater and turned the blue dial to about 73 hoping it would heat to around 78 since there’s a 5 degree difference then plugged the heater back in. Checked back 2 hours later and both thermometers still read 83°. At that point I already had the betta fish and figured it’d be better to acclimate the fish already then take my chances spending more hours recalibrating the heater. That was last night, as of this morning the thermometers still read 83° and my betta fish is doing good. Am I doing something wrong with calibrating the heater? Is it urgent that I get the temperature down or is my betta ok with 83°? Ideally I would’ve liked to lower the temp to 78 so acclimating my betta to the display tank would be easier, but at this point I’m a little afraid to mess with the thermometer seeing how finicky it’s been with me.
