What are your numbers? Did you make any changes to the tank and/or maintenance schedule? Was is overnight or was it a gradual decline of the corals?
 
I am actually in the car going to blue line coral but I will test again when I get home. This was what I was at yesterday
Ph 8.2
Nitrite 0-0.5
Nitrate 2
Alk 8.5
Ammonia 0.1
Phosphate 0.04
 
All the frags I have had for 3months tank is 6 months old light is 6 months old and is a hydra 32hd do you think it is shadded

It could be, look from the top to see if the affected area is visible. IMO a 3 month old tank is a little early for SPS but not impossible. I look to keep temp, salinity, ph, alk, cal, mag, nitrate, and phosphate as stable say possible. SPS=stability promotes success.
