Need help Dying SPS

[howdy20012002]

actually, i don't think that it has ever really recovered from the move here from Claresholm where i picked up the tank and the corals.
The temp is around 82 right now cuz i turned it up to help get rid of ick on my Regal Tang. But the previous owners had their tank at 82 all the time as well..so i dunno
the other one is doing great
i have like 2000 gallons per hour flow in a 90 tank...lots of movement and i have 2 400 MH and 2 110 w VHO Act
the parameters are all fine
I use tap water that i treat with prime.
Everything else is the tank is doing great
So i don't know
