I think you be ok to add the rock back in.arconom said:Now what do I do with the 5 beautiful Pieces of rock that I took because they had the same stuff on it? I took them out since in the beginning they were the only rocks with the stuff on it little did I know all the rocks have it.
Can I put some of them back in? It shouldn't make a cycle right?

I know one thing, i got one of the rocks out of the reef tank that had the red algae on it just to try out and put it in my FOWLR tank the algae die out in two weeks.
That tells me the algae likes clean water and high lights.
