What would you get? Skimz SM 121, SWC160, Nac6A, Nac7 or NAC9?
 

If you had a 66 gal tank (SPS dominated with three mid size (3") fish) what would you get, if you had to choose between these skimmers and why? Also i am trying to find out the size of the neck of the cone Nac7 skimmer, does anyone know ?

It is stated that Nac7 Cone skimmer is 9" at the bottom but what are they at the neck in inches? Almost looks like the chamber of the Nac7 is similar diameter at the top as Nac 6A and if so the these two should have very similar performance in terms of contact time and air to water mix ratio especially due to the fact that these two have the same water pump atman ph2500.

And yet Nac7 is rated for more gallons.

I'd like to overskim so this is decided, but still wonder what others think.
thank you.:smile:

Nac6A

NAC7

SWC160

Or
SKIMZ SM 121

I checked mine: 4" across the neck. (NAC 7).

Any reason why you're decision is limited to Bubble Magus?

500 l/h air intake, small footprint, price, easy to clean, silent pump

If money is an issue, get A nac6. For the $50 more I would get a nac7, cone skimmers are much more efficient.

If footprint is important, the nac6 will fit in more places than the nac7

I love my NAC7 from BWA.
Pulled out sooo much stuff that it astonishes me every couple of days!
Another plus: it is heck of a lot more easy on the wallet than most full-sized skimmer.

how much are these two (NAC7 & NAC 6A) at your store?
What would a shipping to Vancouver cost?
do they come with pin wheel or mesh impeller ?
what is the neck diameter of the NAC6?
220volts or 110V?
thx.

swc 160 cone

I looked it up and it looks a lot like a Nac7. Even pump is the same.
Is SWC 160 cone cheeper? who makes it?

I saw that OA was west coast distributor for SWC for just a short time. Was kinda wondering why they aren't anymore.
I need a new skimmer for 110 gallon rebuild and thought about both SWC and Bubble Magus but am having second thoughts about both.
