It’s ideal to run a reef in the 78 degree range but not required.

I used to run metal halide and my tank got up to 82 degrees no chiller just home AC.

I have a mixed reef tank and run keep it at 76 but the lights inevitably bring the temp up to 77.2 during the day. House temps don't go above 75 in the summer so no chiller is needed.

As long as you're in the safe range and the temperature is stable with minimal fluctuations, ie: not more than 2-3 degrees during the day, then you will be fine. Your corals will adapt, but some may take longer than others.

I went and picked up an ink-bird controller this weekend. I had my heaters plugged into the apex clicking them off and on. I put the probe in the tank just for kicks and it was reading 77 while the apex in the sump was reading 79 in the return pump chamber. Where is everyone keeping their probes? Not meaning to hijack this thread.

I have in both locations, in-tank, and sump. If the return fails, you will be heating the water in the sump and not the water in your tank, plus you will always have that difference in water temperature as well. Learnt this when I was setting my tank and decided to put one in the tank as well.

I would think just putting the sensor upstream of the heater in the sump would suffice. That way if the return does fail you are still covered from at least overheating your sump.

Small fluctuations with the apex big fluctuations with the ink-bird and ink-bird probe in the tank.

I don't trust it that way either. I have Apex, three heaters, each with its own controller/sensor. Being in IT, I bring the mindset of "disaster recovery and business continuity", so I tend to not take many risks. You have heard about Murphy's law, right? Then I add it is not IF it happens, it is WHEN it will happen. :)

Well I’m super paranoid! A few months back I had a glass one explode and nuked the few sps I had and my clam. I really wish there were a way to get away from them all together but my wife keeps the house igloo cold all the time.
