Here are a few more pics if anyone happens to check back on this thread. I took a picture of how it spreads to the sand (in little spots - this took about a week to develop), and another macro of the stuff on the rocks. It grows in the lower part of the tank, in lower current areas.
I like that comment about fast=bad, slow=ok - this was something that has developed over a month... My big worry was Cyano, but I've heard it comes very quickly. If it is some kind of coraline, it is not like any I have seen from pics online.
So if it is somewhere between - is there a point where too much of it can be detramental? How do I curb the growth (I know I could also try to get rid of it completely, but if it's not harmful, I would rather not).
Again.. I'd appreciate your feedback.

Try to increase the current in the affected areas. You can siphon what is on the rock and sandbed out.
You could reduce your photoperiod as well, most people have their lighting on 10-12 hours a day. I don't know how much that will help though as cyanobacteria isn't fueled by light.
