Bubble Magus BM-NAC3.5
Cone Protein Skimmer

SKU: 210107

  • Incredible Value By Jack on 5/29/2014

    I have been using this skimmer for over a year now in my 20g in a small 10g sump at around 6" of water and this thing is a beast (the recommended height is way too much). If you can't fit a skimmer with a side-mounted pump in your sump, which I couldn't, this skimmer is absolutely amazing and the price is something else. I feed pretty heavily on a daily basis and have to empty this every 10 days and I have a very nasty, opaque, black skimmate. Even though the water column height is drastically cut due to the bottom-mounted pump, with mine set to the bottom of the collection cup, and after 2 days of skimming, you can't see a thing because the entire neck and entire skimmer cup are filled with dense, long lasting nasty foam.

    While there are a few drawbacks, the price totally negates them. The construction is a little shoddy (what do you expect in a $180 Chinese knock-off?) - I have a small leak in the seam on the cone, but that plugged itself up with skimmate and salt creep so no worries. As long as you take care of it, it'll serve you very, very well for a long time. Make sure you remove the pump every 4-6 months and completely pull it apart to remove calcium carbonate, biofilm, and the other gunk and clear out the venturi and it'll never let you down. Very simple construction and very easy to break clean.

    My biggest problem with this skimmer is the noise it can make if you have a very, very quiet system without a silencer. I have a herbie and very quiet return, so the skimmer is the loudest component in my tank. Since it doesn't come with a silencer installed, you WILL hear the air intake - but the rest of the pump is quiet with negligible vibration. However, even the least handy person can build a silencer out of a pill bottle (I built a huge tennis ball can silencer) which will take care of your noise problem all together.

    Get a skimmer with a side mounted pump if at all possible since you get almost 30% more height. If you can't, this is an invaluable piece of equipment you will be happy with.
  • I would NOT recommend this to anyone I know. By JAE on 2/24/2014

    I've had this skimmer for about 8 months which it only worked max of 3 months in total. I've had to replace the pump twice due to manufacture issues. Doesn't pull out as much as it should when it does work. For the price just put a little more towards a better skimmer. Only thing the BM has on a good note is a small foot print.
  • For the Price & Footprint......Good Skimmer! By Eric B on 2/10/2014

    I have only had this skimmer set up for a day, but it broke in quickly and has already started to pull out a light tea-colored skimmate - after less than a day. The foam in the column is pure white, and has good turbidity. Given that it takes up about the same room as a reactor, and costs less than a couple hundred bucks, I am pleased. I do, however, look forward to seeing the skimmate improve as the break-in progresses.
  • dial it in By Kev on 10/24/2013

    If you're like me you research profusely before a purchase. I searched and talked to some of the local shops around my area. When I asked the shop I buy my coral from what they recommend, the owner told me that he would go for a bubble magus. I would strongly recommend it to anyone on a budget! It amazes me that BRS does not put the recommended stamp on it.
  • Great Skimmer! By Evan on 5/29/2013

    This is a great skimmer. Though, I got off to a confusing start. I have had skimmers before so I knew how to assemble a skimmer from experience. I assembled the Bubble Magus and placed it in my sump. I had to adjust my water level a little bit. Plugged it in and no bubbles. I took it back out to look it over and everything looked fine. Check the pump and the airline tubing and everything looked fine. I tried blowing down the airline tube that goes to the pump thinking there was debris in the tube. There was a thin layer of CLEAR plastic on the airline tubing elbow that goes into the fitting on the pump. Essentially the factory left a piece of plastic that prevented air to get to the pump and not cause bubbles.

    Its been running for about a week and starting to pull out darker and darker skimmate. So far about 3 cups. I have mine in about 8 inches of water with the dial set at just barley under 5.

    Great skimmer! Check for factory defects or left over plastic when cleaning before placing in your sump.
  • Good product By Tom on 12/28/2012

    This skimmers well built. It is also REALLY quiet! That's a big plus in my book. I love the small footprint on this skimmer and it's really good for tanks with small sumps nor limited space. Overall is a great product at a great price!
  • Quality product, bad instructions By max on 11/9/2012

    Another speedy order from BRS, product looks great out of the box extremely happy with it, great for confined space, will be using in a aqueon proflex sump 1, needs good cleaning, but ready to go
  • Perfect for small tanks By Casey on 10/30/2012

    This skimmer is very easy to maintain, provided it is placed somewhere with a constistent water level. Best skimmer I've used thus far!
  • Good Skimmer By Bryan on 8/9/2012

  • Just WOW By Codebrew12 on 1/10/2012

    For the money there is not a better deal. I hate to even say "for teh money" because this skimmer is top notch. You will not be sorry you purchased this little gem.
