Anybody running the BM99 I believe that the US version has the Maxijet pump and the Euro one has the Jet pump. Thanks in advance

Fishybiz has one and loves it. It's the maxi jet powered unit.
I forgot what page number it's on but it's in this thread a few pages back (pg 44?).

Strange thing about these skimmers is that while they look like they waste alot of space that is void of bubbles, the bottom of the bubble curtain is strangely calm and seems to just hold bubbles in slow suspension. I too was skeptical of these skimmers but after watching these things, there is no doubt IME that they perform as well if not better than any other skimmer I've owned.

7in of water did nothing for me. The pump seems to like more height and pressure. From what I observed, the higher the water level the lower the pull of bubbles down the body of the skimmer (better dwell time).
Just my experience
BTW Had to put my BK 160 mini on mothballs for a while until I get it in a bigger tank. The NAC6 destroyed the Bubble King mini in terms of production! NAC6 back in!
No knock on Bubble King (great skimmer), the NAC6 just seems to work much better in my low nutrient system.

Close the wedge pipe until the bubbles break even with the bottom floor of the cup and give it a few hours (maybe sooner depending on water quality-DOCs). You should start to build a foam cushion. The unit should be run optimally at 10 inches but some have good results from 7 on up. You'll be fine!
Note: I countersank all the holes in the NAC6 bubble plate and drilled 10 1/8in holes around the side 1/4 inch from the top plate. I had high hopes of reducing turbulence but essentially only created a finer bubble (which is good!). I'm thinking that I should have only drilled the outer two circular rows. It seems that with the countersunk holes closer to the pump outlet, the bubbles collect with force at those points in the cup and don't distribute as well to the outer circumference holes. It still works well with no adverse effects though. I took pics of the plate mod and will post soon.
I was pleasantly surprised to find that my bubble box on my SWC skimmer fits perfectly on the NAC6 pump and installed the box at lunch today. WOW, talk about a difference in turbulence!!! It is the box that mounts on the SWC extreme 120 cone. There are real good pics of the box online at ************ and glassbox. The bubbles in the body are much less turbulent and fill the body quite a bit more. I think we may be on to something here!!
I didn't get a chance to see the results yet because it was back to work as usual but when I get home i expect to see a much better foam head.
I will let you all know.

Just noticed you wrote "2"? Is the mark on your wedge pipe set at 2?
If thats the case then somethings wrong because your cup should be overflowing at 2.
5 is wide open and 2 is nearly closed. At 5, the water level in the skimmer will be at its lowest point. At 2 it should be at the top blowing junk into and overflowing the cup. Where is your water level in the skimmer? Sorry I missed the info earlier. Running the skimmer at 8 inches will require a more closed wedge pipe to get the foam head high enough but if your at 2, something doesn't sound right. At 8 inches mine ran well at the 3 setting.

I took my NAC6 out of the sump to clean all the crust and junk out of it, cleaned the pump and all that but I didn't put the diffuser plate back in. I have a theory that certain skimmers perform well with them, but in other instances they be a hinderance so I removed it. If you look at the higher priced, larger skimmer like Deltec and Bubble King, etc., they bubble plate is large - taking up almost the entire girth of the skimmer. Additionally I've noticed that most skimmers that have them tend to be larger (taller) than most "hobbyist" level type skimmers. Then I started thinking about the old school Euro-reefs, ASM's and pretty much all of the other skimmers that perform well without the bubble plate.
Now, my skimmer's body is almost completely full from the top of the pump - up instead of a distance above the bubble plate. I think I'm going to leave it this way for a little while.

These skimmers rock....I have a NAC6 on my 70 oceanic setup and it was the best $150 I ever spent in this hobby.
Am looking to get a bigger one for my new 120 tech tank but not sure which way to go. I'm sure the one I have is gonna be too small.
Maybe one of the newer cone models?? What's everyone using on their tanks around this size??
Thanks

The skimmer is working very well now, my guess is that my skimmer needed sometime to break in since upgraded my 55gal to total 100 gal system (75gal w/ 25 gal sump) 1 week ago, it might just be the water was too clean
. As for now, the wedge pipe is still set at 2 and the water level in the sump is @ 7.5 inches. I know most of you did really well running the skimmer at higher water level, but I'll give it a shot to see how it will perform in the long run.

Tried the countersink mod with the NAC6 Bubble plate.
Good news is it started to work well.
Bad news is when I unplugged the skimmer for repositioning, the pump would not re-start.
Too much fiddling! I took it apart and found nothing unusual except it wont restart. Tried blowing in the airline, tried checking the mesh, tried re-seating the bushings, tried soaking-nothing! I will get a new pump and post some true results.
In the mean time, heres some pics of what I did.
Along with the SWC bubble plate that I tried as well.
