Reef Octopus or Bubble Magus?

I have an NAC6 and I love it. It was OK with the stock impeller, but now I am using a Pinwheel impeller and it has increased productivity exponentially. It moved from my 100g FOWLR to my 60g Dual nano System and now it will be moving to my brand new 75g I am setting up. Under light bioload it doesn't pull that much, but in the FOWLR it pulled thick black STINKY gunk.
 
I heard the bubble magus has a LOUD pump, whereas the reef octopus is generic and not strong enough. Hmm.

How is your pump's loudness? Also...any microbubble/break-in period issues
 
Pump is nearly silent, the fans on my Nova Extreme Pro are louder. Absolutely no microbubbles. No issues with break-in. I did run it in a vinegar/water solution for a couple hours prior to install on the tank.
 
No problem, I think most of the people who claim it has a "noisy pump" have a broken/misaligned impeller and don't even know it. It is the same exact pump as the SWC120.
 
I had the NAC6 too - it was a great skimmer IMO and I only used the stock meshwheel.

I'm running a SRO1000-INT Octo right now with the Bubble Blaster pump and it's a great skimmer too. I know it's a little different than the one you linked, but it's the same skimmer with a different pump.

Both great skimmers for the $$. Either way, I don't think you can go wrong.

The only major difference is that the NAC6 is a lot bigger than the Octo - but the NCA6 pump is located under the reaction chamer - the Octo's is outside the body. If size constraints are an issue, that may be something to consider.
 
Yeah I really think I am leaning towards the NAC 6. Quick question.....would it work in this sump design?

Is there a reason your chambers are so tall? The NAC6 will work in the skimmer area, but you would have to put it on a platform. You want it in appx. 9.5" of water to function at its best.
 
Our chambers are so tall ..... because I dont know lol. This was our first attempt at building a pump and I thought most people made them this high. Also..if it helps, this sump is a 20 T. Are the chambers too tall? :(

Not necessarily, are you sure you have enough room in the sump to account for drainback in the event of power failure?
 
You fill the tank with everything turned off until the water reaches right under the top of the sump. I am worried that when you turn everything back on with baffles that high there will not be enough water to keep your return pump submersed.
 
Yikes....now I'm worried!!!!! We bought a mag 5 return pump I believe. We are buying our tank in "pieces" so we still havent tested anything out

Also, which baffles would you recommend we cut shorter
 
I would go with a 9.5" water height for the first chamber and an 8.5"-9" water height for the second. I would also increase the size of your skimmer chamber by 1" to accommodate the skimmer and your drain plumbing comfortably.
 
The way it is now you would have to build a platform for the skimmer, Should be fairly easy to do with some eggcrate. You will have room for about 6 gallons of drain back. Im not sure what skull means about the return pump running dry. There will be the same amount of water after the power failure as there was before the power failure. Your return chamber is fairly small so you may want to invest in an ATO, they are well worth the price.

What I mean is that with the sump full during the initial fill when you start up the system and the skimmer fills, the tank.fills, and the plumbing fills there may not be enough water left for the pump to be submerged. More common with small sumps.
 
If you used scilicone when installing the baffels, yes you can remove it with a razor blade and redo it. I am assuming from your drawing it's a glass tank and your using acrylic baffles. If so, scilicone does not stick well to acrylic. Try putting a bead on each side of the acrylic to help hold it. ;)

If it was my sump, I'd do the first baffle at 9.5" to accomidate the skimmer. Second baffle at 1" above the bottom. Third baffle around 5" and the last baffle around 6". That is unless you have a major reason to have the fuge area so deep.

You can also put in another under baffle like the second one between the fuge and return pump area to also help keep bubbles out of the return pump area.

With that type of setup, you will have less water in the sump which will allow for more water from the tank when the power shuts off and it backflows.
