Have you determined the cause?

I've annoyed my sps a number of ways over the years and it's hard to say exactly what was the cause each time. I am fairly certain these have caused issues:
Salinity too high
Phosphate/Nitrate too low
Alk too high

Alk too high

Peppermint shrimp snacking on SPS
Various fish snacking on SPS
and any equipment failure (auto top off, skimmer, cavitation in a pump, exploded heater,...) that caused parameters to change outside of acceptable boundaries or just created general instability or rapid fluctuations.

Beside pest nutrient is the main cause for sps decline. Alkalinity swing is not enough to kill it if its happened over time. I lower my Alk from 8.8 to 7.0 in 4 days and my sps are fine. If you don't have enough nutrients in the tank you will see your corals dry up no polyps extension and turning brown or losing color. ULNS like zeovit is hard to keep because you have to feed and dose your tank everyday and u need to follow the instruction no slack off or lazy. In the ocean sps feeds all day 24hrs that's why they can grow up to 6". In our tank is too clean nothing to feed until you feed the fish which is 3 to 4 times a days. I feed my tank 8 to 10 times a day plus amino 2 times lol.....

Forest fire smoke being drawn into the tank via the skimmer was causing a seasonal SPS crash for me until I figured it out. Even the mostly air inside the house was enough to do it. External skimmer intake while I was out of town REALLY killed and damaged my SPS.

So many issues and mistakes/learning experiences over the years. I will just list a few that I know the cause for sure.
-Bleaching from new mh bulbs, now I decrease lighting time for a few weeks.
-Browning from alk swings and coral pests
-RTN/STN from alk swings
-Pale color from too low nutrients

Base up recession the years that it was just the house air.
After I routed my skimmer intake outside, it was by the time I got home from out of town, 10 days. The majority of my acros had withdrawn polyps and had darkened way up , kind of an ashen gray / brown, all the way to the previously growing tips. Kind of like when you have a frag go dormant. Sat that way for a week or so and then fairly quickly started dying from the base up. Only was able to save a few one inch frags from 6 inch colonies, and those frags sat for quite a while before they started growing again.

For my contribution i had a birds nest colony rtn from a piece of hair algae that got tangled in it. I couldnt get it out so it died. The piece was probably 5 inches long lol.
