Hi, I have a super quick question. There is a fowlr tank at my favorite lfs and in it is some LR with that is covered with coraline. I am going to get my calcium level up and when I do, I am wanting to buy a piece of this rock to introduce coraline to my system. This fowlr tank has been setup for a long time and I was wondering if I have to qt the lr. If so, for how long?
