This morning, I tried to take a look at the mouth of my hammer coral before lights came on. The polyps don't look bad from above, but I couldn't see what the mouth looked like since it was covered by the polyps. I also didn't see any recession in the flesh of the stalk from the side although this is the side opposite of the problem area and I really don't want to move the coral and potentially aggravate him if there are no issues.
One thing I did do was to change the set temperature on my Inkbird to 79F from 80F. My tank has been heating up to 81F at which point, the fan kicks in and brings the temperature back down to 80F only to repeat this cycle. I don't know if temperature is causing my hammer coral to act up (if he is), but it doesn't hurt to lower the tank temperature by 1F.
I unplugged my heater so that it doesn't interfere with the temperature for now until I can program it to 76F at the next water change.
