So I just bought my tank and it was used as a FW tank before. It came with some tank decor. One of the pieces is a rather large fake piece of coral. Can I use this in my FOWLR tank? There is a hole in the bottom of it that I am afraid might trap water and cause some bacterial growth. Should I just stay away from it? It would just save me a few bucks worth of live/base rock
Here are the pics of it:
