Marco rocks .. rubble zone ?

[reefrookie379]

Hello,

I have had my tank running for over a month now and fully cycled. I always loved the look and idea of a rubble zone. I was thinking about breaking up some extra Marco rock I have from my aqua scape. Will it be a problem to put this dry rock into my system now to create the rubble zone.

No, it will take a while to be seeded, can block whatever was under it somewhat, and will make some fine white dust float around for a bit, but it should not cause any real issues.

Expect some normal 'ugly stage' sort of algae initially, but in an established tank it shouldn't last as long or be as dramatic.
