I have seen Xenia grow in all dkh ranges. I suppose some colonies do better at certain levels but as long as its stable and within range it should be fine. I have seen it stop pulsing at very low levels though. under 6. which in my opinion its too low for a mixed reef.
Xenia do need iodine in the water so you may want to get an iodine test kit and dose that or look into it and do some research on that.
I have had luck removing it off rocks using a torch! thats right. We took the rock it was on out of the tank and used a propane torch on that area of the rock and it never returned. the torch can be bought at any large store like home depot or walmart for less than 20 bucks.
Hope that helps a bit.
