180G Office Reef Tank

[fishoholic]

The Nac-7 skimmer is rated up to 90g, pretty small for a 180g plus sump. I have a nac-7 running on my 34g cube/20g sump, a bit overkill but I figure if I ever upgrade to a 60g cube I'll be ok skimmer wise.

Also starting with mostly dry rock will take 6 months to over a year before becoming live rock. My advice is to stock the tank like you only have 20 pounds of rock in it or use mostly live rock and only a small amount of dry rock.
