Need help with declining favia

Hi, We got this favia about a month ago.(Picture in Gallery) It puffed up the first day or so but has not really inflated like it should since. Its bleaching around the skirt. I had him on a rock about 1/4 up the tank but about 1 week ago I moved it down to the sand....about 36 inches from the lights. I've been careful to keep him at least 6 inches from other corals because I'd been warned about his potential to sting them.

I feed cyclopeeze and various frozen shrimp formulas everyother day and DTs. I have never seen tentacles or sweepers out on this guy. Everything else in the tank is looking quite fabulous...even several corals who are suppose to be much more difficult.

Water Parameters are:
PH 8.13
Alk 4.91
NO2 0
NO3 20 ( I know, I know.. we are currently dosing with AZ NO3)
Ammonia 0
Calcium 625 (my husband says the result of frequent water changes)
Salinity 1.025

Tank is 225 gallons,
Filter Eheim 3
30 gallon refugium
protein skimmer

Lights:
2 400 W 14,500 kelvin MH
4 T-5s 54 watts each


Can I lugol dip him to see if there are any parasites?
Should I move him into a shady spot?
THANKS in advance for your help....
Romayne
