This stuff has been growing on my rocks for a while and I cannot figure out what it is or how to get rid of it, short of pulling everything, bleaching and starting over, which just isn’t an option to me. Cyano is not the answer….it encrusts similar to coralline but does not have a calcium base. It is very hard to scrub off….plastic bristle brushes do almost nothing to it and nothing eats it.
