Have an Aqueon submersible heater on my 75gal. It's a pretty good heater if I do say so myself. I have this 200 watt heater (suitable for my 75gal) in my sump. Question is will it be working better if it were in my actual tank? Last night before I added 12 black none tetras to my discus tank the temp was 83 * right now that I woke up to feed my fish the temp was at 78*-79* don't want any fluctuations like that that may affect my discus. Or should I just set it a bit higher now that the climate temps have gone down?
