For reference, my tank ranges from 76 degrees in the winter to this or even higher in the summer.

I kind of doubt it specific to heat and instead could be trace-related. I have new coralline popping up on a daily basis on my front panel which drives me up the wall. The rest of my coralline is still dark red and purple. Again, my tank has been over 84.5 degrees for last month and this week thanks to our heat wave, is sitting at 85.2. Last september, it hit 86 degrees. Still no changes in coloration. I do periodic water changes with reef crystals, so maybe the coralline is getting what it needs from that.
No it's not a brownish growth on top of rock... Its hard to explain. I just ordered fresh Cal and Mag test, mine where dated...lol. I never just Cal and Mag in all these years as I just have never had to. One very solid system... till this. lolIf your tank doesn't normally hit 85 then that could be the issue, yes. Corals are more resistant to high temps if they've been exposed to it before - but if it's unusual for your setup that could cause some issues.
Parameters would help.
Also wondering- is the coraline itself brown or is brown growing on top of it?
What is Calc and magnesium at

I will check ALK as I only check it about every two weeks.. Via apex and doser... Dosing Tropic Marin and it was dosing at 9:30 yesterday I saw it.Probably the heat. If you didn’t add any new supplements to tank and alk and calcium have been steady. I think it’s the heat. Only other thing I seen kill coraline is exposing to air too long and big swing in alk.
Its always good to test at least once a month. If not have them around when you see something off. Let us know the numbers my bet is the mag will be in the 1100 range.No it's not a brownish growth on top of rock... Its hard to explain. I just ordered fresh Cal and Mag test, mine where dated...lol.
