Hi all,
I've had a Steath running on the tank in my .sig for a couple of weeks, now, and, until yesterday, it had maintained a nearly steady 78 -- just where I wanted it.
So, yesterday I did a 2g water change to dilute some of the tannin staining, and today I notice the temperature has gradually dropped to 76. I didn't touch the setting dial, but I did unplug the heater while doing the water change. (And, yes, I plugged it back in. :silly: ) Is this normal? Did unplugging and plugging mess something up? Is the angle of the heater throwing the thermostat off? (You can see pictures of it here.) Am I concerned over nothing?
