I've always noticed that I get small amounts of cladophora growing on any driftwood I have in the tank. It tends to be slow growing and never any problem as once every month or so I just pull the few bits out that have grown. There is no hint of any other cladophora growth in the tank, not even in the thick mat of HC I have. I'm curious to know if there is any reason why it likes growing on driftwood so much?
