Including Alkalinity, Calcium, Magnesium.
Read up on Sps pests like red bug they can cause polyps to retract.
A blind guess is Alkalinity is to low or red bug but there are to many variables to know for sure.
How do you keep up you alk and calcium?
I went a little overboard with info on the thread linked below but it has a lot of useful info. Scroll down to the bottom of the link.

Well after reading your post on SPS, then I probably shouldn't have posted this..nor really keep SPS... My philosophy is "keep it simple" and low tech-maybe it's the girl in me :) (all of the equipment and various parameters are way too complicated). I don't dose anything because I don't test other than salinity. I test occasionally for pH but it rarely changes. I do 25% water changes in my 120gal every two weeks and vacuum out the 40 gal sump of detrius. I have a Octopus 200 skimmer and chaeto in my rubbermaid sump. I have (6) T-5s-wish I had 2 more. I've had this tank for 3 years after upgrading from a 3 year old 55 gal (total of 6 years). That's pretty much it so I can't answer any of your questions above. I better duck and run!
For being low tech, I think that the tank is pretty good if I say so myself. My blue acro, tubs birdnest, green birdnest, yellow millis, staghorn, LPS, and softies are doing great. I wouldn't say that they are growing like weeds (other than my yellow colony polyps and gsp), but they are growing and have pretty good color, I think. Or maybe I'm used to seeing my tank and think it is normal? :confused2: The GSP are my indicator coral. If something is wrong with the tank, they usually let me know quick.
My salinity slipped up too high for the last few weeks to .29. Maybe that played a role in the millis. I got it back down this past weekend. Let's see if the fuzzis come back....
Pretend I never posted this :)
