Adding dry rock to existing tank? Maybe?

[Mafiaboy]

Hey guys,

I was thinking of adding some more rock to my aquarium, is it safe to add more dry rock? I assume it will enter some sort of cycle? Anything to be concerned about?

Cheers

May get an algae outbreak or dynos are also a possibility. The rock can bottom out your po4 fast. I have done it in the past and algae followed within a week.

You can add more dry rock. It will go through the uglies just like the other rocks.

I would soak the dry rock in old tank water for a month or so before adding.
