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

|   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. |

|   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? |

 LOL i might just boost up a flow a little on my large DIY downdraft air driven skimmer and be on par with BK on TOC removal ! LOL, because my skimmer is driven by a huge air pump, and 2 air stones last up to 6 month. A waist cup wash on it takes less time to clean then on my Deltec MCE600 |
