[Reef Supplies]

They are both great skimmer but Id have to go with the In-180 if comparing the 2. We sell both and we love them both, they are both close in price NAC $249 and IN-180 $299.

The biggest difference between the 2 is the foot-print. The IN-180 is huge where the NAC 7 is very compact. I would post a comparison picture but the NAC are on BO.

Here is a visual of the in-180
