First allow me to say, 'Welcome to R2R!'
It's hard to say if that pink is the start of some coraline algae, a very good thing and most likely IMHO. Or it could be some cyano bacteria, a not so good thing but not a huge issue and far less likely.
If you would like to get a lot more replies to your post, we could move it to one of a couple other forums that get a lot more eyes than it does here. But if you are part of this group (Florida Reef Keepers) and want it to stay here, that's perfectly OK as well. I'm just offering so more people might give you more replies.
Good luck. I'll follow this thread to see what you would like to do.
