Ace, I think that is a millipora. It is really starting to grow up and should start to sprout more upwards. And yes, i am at the hair algae phase. I am using Algaefix Marine, about 1.75ml every three days and it has dramatically reduced it. So, hopefully, in about 30 more years I will be done with it.
Dixienut, that is actually a Duncan. But it is a big duncan. When I bought it it had a few medium sized heads and sprouts. Since I bought it it has grown like wildfire. It now has huge heads (about size of half dollar) and there are several smaller heads (about the size of a dime).
