Also, I went to RC's tank volume calculator and apparently my display is only 8.3 gallons, which means I have ~22.7 wpg
12 X 14.5"/144 = 1.20 sq. ft.

188 watts/1.2 sq. ft. = 156 watts sq. ft.

100 watts/sq. ft. is normally recommended as a minimum for a "typical" SPS type reef tank (21-25" deep). I'd say you are a bit over the miniumum for a 12" deep tank. Probably over double that.
