Went to this guys house today from a forum, he gave me some free frags! such a nice guy, but anyways i was asking him about how he got his coraline algae to grow all over the place. So i asked him for a piece of his rock. He told me to shatter it into a lot of piece and spread it all over my rocks...think this would work? waht i did so far was run the rock on other rocks to try to get some of the algae off...any suggestions?
