Thanks! My gut feeling is the same - pristine SPS tank = alveopora unfriendly. I have some SPS (tubinara cup, pachyseris, Monti cap) that do well, but not acropora.
Did you ever frag any of your allie's? Any suggestions on cutting the skeleton? I know it is fairly porous, but the piece I want to cut is still about 3/4" diameter by 2" long (skeleton size). This allie (the pink one) has grown around the rock it is on, so I can't remove it for the fragging.
