I have in my 29 gal reef a dark algae. I can't put pictures up right now, but if anyone knows about this help would be appreciated. It is a drak, purplish-black algae, and is stringy. It grows very fast, almost doubling its area in one day. ANy ideas on what it is and how to control it are wlelcome.
