Heater range is 80.6 - 80.8. That's high for my taste but until I get some fans to lower it throughout the day it's set that high to keep the tank consistent.
Note in the first graph that the graph never drops to 0, it appears there is always at least one heater running. I've never monitored heaters like this, it's possible that heaters normally cycle throughout their heating cycle. I'm going to separate the two heaters later and monitor their power consumption when on and see if both are doing this or if it's only one of the two. They are Cobalt Aquatic Neo-therm 150w heaters. I'm also realizing I probably need some extra wattage.
