Anyone had experience with either of these skimmers? How did they work out for you? Good buys?

I've had both and the Nac-7 is better
Thicker foam

I've had the vertex In-180 for almost 2 years. Once in a while the pump does get a little noisy but I've been extremely happy with the output and how little I have to fuss with it to keep it dialed in.

I bought a brand new IN-180 and its the worst skimmer I have owned. Terrible noisy pump with restart issues brand new right out of the box. No more Vertex IN's ever for this guy! Only Vertex skimmer I would buy is a Alpha Cone which I have owned and there awesome skimmers. I am not sure about the BM-7 as I have never owned one.

I dont have live stock in the tank yet but from what I can see the NAC-7 is going to be a really good skimmer. It's dead quiet, nice "froth" of bubbles in it, easy to set up and clean, solid construction.

It's not what your asking but, I had a RS180 (Euro reef) essentially the same as the Vertex IN-180. It was a great skimmer also. Not the same pump as the Vertex though.

On a side note. I heard that Vertex is coming out with DC pumps that will be controlable via the Cerebra and possibly on their own as well. Integrate with their lights for feeding mode so your skimmer ramps down and a few other cool features. Might want to consider that as well.

I had an SWC 150 BMK (non-cone, straight cylinder) - used the same atman 2500 pump that is found on the Bubble Magus NAC 7. FWIW the SWC configuration of the same pump pulled more air than the BM unit. I was very happy with the SWC unit and for $200 brand new you couldnt go wrong.

I was then given the opportunity to test a new skimmer from my LFS. The pump pulled just as much air as the ATMAN 2500(approx 20-23scfm) but only used 13w! Thats less than half of the ATMAN. Better yet the bubble quality/production on the new skimmer was phenomenal. In the SWC i didnt get a continuous column of white bubbles -there would be pockets of water that would disrupt the bubbles making there way up the column. With that said the SWC unit still performed well.

Words only do so much - Here are some pics.

(FYI my tank is only 50 gallons - heavily stocked - sps dominant - fed two small pinches pellets daily and a 1/3 cube of frozen food - 5 gallon water change every 7-10 days and i run 75 micron socks. Nothing else is dosed except calc/alk)

SWC 150 BMK after about 7-8 days of skimming - fully dialled in;


my new skimmer;

unit was given a vinegar bath for 48hrs. Foam production pic below is 5 minutes into it being run in the sump for the first time.

air draw

i found the best depth for the skimmer was 6" - I cleaned the cup THOROUGHLY and ran it for an entire week. During that time i changed the filter socks once and did one 5 gallon water change.


bubble action - notice how the break from fine bubbles happens low in the neck transition? Any higher and the thing over flows. Its a very powerful pump.

I have the NAC 7 and I love it. Foams really well, solidly built, easy to put together, easy to dial in and the cup is easy to remove for cleaning. :thumb:

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

Footprint 14″ x 10
Height 24


Footprint 9.4″ x 7.8″
Height 20"

Good luck with your purchase

We have a Vertex In-180 skimmer and we are extremely happy with it...pretty good skimmer for the price.

I have hands on with both..... vertex seems to be built a little beefier but is noisy and large..... BM seems a little plasticy, but is quiet and has a nice small footprint..... the pumps on both have had issues......but one cant expect too much from a cheap skimmer:wink:
