Sargassum

[Troy F]

Mine never did, it grows rapidly and is easy to prune so it must be soaking up some nutrients. The only thing about it I don't like is; it's kind of ugly. I don't think it is unicellular like caulerpa but I don't know a heck of a lot about it. I have oodles of it in my new system, I'm sure it'll start taking off as soon as the other alga is consumed/removed.
