Temps are fine it runs a high of 82 with all the lights on and down to 78-79 at night.
I am dosing 15 ml of spur2 once per week it is a 400 gallon system.
all mushrooms are doing fantastic ric's are doing well getting good coraline growth my pink tip eligance is as big as ever some of my sps are not doing too bad and others are still alive but going brown the ones that die seam to be going through a slow painful death it takes about a week or two.the corals get feed with zeo coral vitalizer every night.

What tip of light are you using? How old are the bulbs? Maybe the bulbs shifted spectrum? Just a thought.

I dose 2ml of spur2 every week or two, too much can take away all their zooxan alage. maybe try cutting back on this, as well, if you wanted to try just dosing the basic four, start, food, bak and CV. until everything comes back on track. its just a suggustion.
also when i started the zeo, i found that all my coralline died, as the zeo was taking all that extra stuff out of the water.

I noticed that the bottle of Spur2 says to dose every 7-10 days, but on the ZEOvit forums they told me to only dose once every 14-21 days if needed. So, if the corals aren't darkening up, don't use it at all. I would quit using the Spur2 until you can figure out what is going on since Spur2 is only for your own viewing pleasure. From my understanding it isn't for the health of the corals at all.

Did you keep SPS corals successfully before you moved to the bigger tank?

dont forget to accomplish a sustainable system before adding chemicals to your tank that you dont fully understand
