Corals bleaching. Need help.

Daniel came over today to help me out and I guess my SPS are going through RTN. I'm not sure why this is happening but we trimmed out the parts that were dying and are hoping for the best tomorrow.

John, there's no temp swing.

Leo, I did testing on other kits and the numbers matched up.

i guess we need pics to find out what's going on.

btw, did you change anything else ? Did you do something with the lighting? skimmer? carbon? ...etc

Nava, the only major thing I have done recently was dose mag and alk. I went through a large major change about a month ago because I killed a bunch of fish when I accidentally added nail polish remover to the tank.
