JPH1970
I have an Eheim Jager 200w on my 29 gallon tank and I had it calibrated as close to perfect as possible. It was set to 77 or 78, I forget
Two weeks ago, I elevated the heat to treat for ich and it seemed to be fine. The temperature was holding steady at 86 F. Yesterday, I started to lower the temperature slowly. It took a while, but it was going down. Throughout the day, the tank temperature was always higher than what the heater was set at. Did it become uncalibrated? Last evening, the heater was set to 77 F and the tank temperature was 80.6(according to the digital thermometer I now use too) and it was the same this morning, about 8 hours later.
I use two thermometers in the tank, one at the left side and one at the right, and the temperature readings on both are nearly identical. The one on the right, opposite of the heater and filter is a tiny bit lower. A digital food-grade thermometer registers the same temperature as those thermometers.
Does water temperature take that long to drop?
