King, I can't seem to get rid of it even if I use ro/di water. Seems like I am feeding my fish a lot. I am trying to feed the fish less. Still getting nowhere with this cyano rpoblem.
BTW, I was scraping the coralline off the glass this morning when I happen on this little guy at the back of the tank near the base of the overflow. It's perched on a dead halimeda that I glued to a piece of rock.
Anyone care to ID?
