I've been reading a lot about sumps as I'm looking at getting one with my new tank (see my other thread). I've read that adding live rock to a sump is good, so I plan to do that. I also want to get a Mandarin after my tank has been running for at least six months.
I'm wondering if it is good to swap live rock between the sump and main tank every month or so, or would it be better just to leave the live rock permantly in the sump?
