Re: Adjusting Iodine levels? Yep, quite sure they are pulsing xenia, as the one I got from a LFS was pulsing in their tank...the rest are frags that I've gotten from people in my local MAS. My Red Sea xenia seems to have responded well to having the Ph raised with some buffer last night, I'll see how the others do once the lights come on.
You add 7 drops a day of iodine and don't test the levels?  Any algae problems?
