I have 2 heaters right now in my 90 gallon, a 200w and a 250w. I don't know what brand of the top of my head, but they are just your typical submersible heaters. The problem I am having is they aren't sensitive enough to keep the temp from fluctuating a few degrees. Right now, the temp is almost 83 when the lights go off in the evening, and then around 81 the next morning before the lights come back on. I have tried fiddling with the heaters to get them to pick up the slack at night to keep the temp at 83 (I know this is a bit higher than I want it to be, but the only way I can get it cooler is to get a chiller, which I don't want to do), then basically turn off during the day and let the lights do the heating. What brand of heater is the most sensitive, that will keep the temp to within a few tenth of a degree? Also, I'd prefer to get one more powerful heater, if possible (the heater would be in my sump). Thanks guys.
