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.

I'm not sure where you got your rating but both Bulk Reef Supply and Bubble Magus' website would seem to disagree regarding the skimmer rating, and every other website I have come across that sells the Nac7.

Yes it is still a bit on the low end for this tank, but I have to work with the budget I have unless it comes out of my own pocket.

The NAC77 (rated at 210-315) would be ideal I think, I just don't have room in the budget right now. I may change this or try and persuade an increase in budget but it's not a top concern at this point in the build.


I realize Dry rock will take longer that usual and for most of my tanks in the past, I have usually let the tank sit longer that a normal cycle anyways before any heavy stocking. I haven't even started to think about stocking yet to be honest.

Right now my main goal is to get this up and circulating water and seeding as soon as possible. I can keep the rest of the office staff at bay regarding stocking until its ready as none of them have a clue about the biological cycle/filtration involved in a salty tank, they will just have to be patient and listen to my advise.
