  • Great Skimmer By Ryan on 2/1/2016

    Tuning it was easy. Before I bought it I read some people said they couldn't tune it. It started taking dark green waste out of my tank right away.
  • Simple, Effective, Overkill, in a small footprint By Damion on 12/8/2015

    I am so glad I went with this skimmer! It is super quiet, has lots of "tunabiilty", and was instantly "broken in" and producing skimmate in a few hours. I am using this on my heavily stocked 90. I have 5 "poopers" aka tangs and 10 other smaller fish, and feed 3 times a day. I don't skim too wet, and get very dark skimmate, and the huge collection cup lasts me about a week. It also has an optional drain for a skimmate locker. The parts are readily available on BRS and relatively inexpensive if needed. It is built very solid and from what I understand, way easier to tune in than a Vertex. This in conjuction with my Methanol denitrator, I keep my nitrates just barely detectable. I am very happy with this purchase!
  • Outstanding By Ronald on 11/22/2015

    This replaced a skimmer that I had been fighting with for 6 weeks. I spent about 20 minutes with adjustments and 6 hours later I had waste in the cup. A few tweaks here and there and it does exactly what it should. Super quiet and versatile I will purchase another Skimz for my next salt tank. The quality is impressive.
  • Excellent skimmer for the price By Neil on 9/8/2015

    It's not at the same level of quality as the Vertex or Reef Octopus but for the money it's a solid unit. I'm using it on a tank that has been fully cycled for only a month. Even though I don't have a ton of nutrients, I could see that it was already starting to do the job. Based on my experience with other skimmers (Reef Octopus), I believe this skimmer will do the job. The unit is extremely quiet. I wasn't sure I needed the DC pump but I'm now glad I opted for it. Small footprint also lets me put other items in the sump. So far I would definitely recommend it.
  • Awesome Skimmer! By Marty on 7/11/2015

    I bought this one to replace my old ASM G-4 Simmer, and I can not believe the difference in quality and performance! This Skimmer is awesome.
    And I can't believe how quiet it is and the footprint size is very nice if you have a smaller sump and tight on Space.
    I have this installed on my 225 gallon tank.
    I highly recommend this Skimmer! And a great price too.

  • Excellent By Bald Reefer on 3/5/2015

    I love DC power, so when I heard that these pumps are over powered and that you have to tune them down, I jumped on the opportunity and I have no ragerts. The skimmer is easy to tune, easier to clean, and super duper quiet. 125 gallon
  • Amazing Skimmer By Eric on 3/4/2015

    The skimmer is absolutely incredible. I purchased one when I was fed up with my cad lights PLS-150 cone skimmer overflowing constantly and being impossible to tune. As soon as I opened up the Skimz Monster SM163 I could see a HUGE difference in build quality. The skimmer really is amazing – best skimmer I've ever owned.
  • Love it. By Michael on 2/9/2015

    What a great skimmer. Especially for the price. It is so quite I can not tell its on. And I love the BRS handles all of the warranty work.
  • Great Skimmer! By _TheGrimReefer_ on 1/27/2015

    Was a toss up between the RO Regal 170sss or skimz so glad I went with skimz great build quality, extremely easy instructions and started skimming the same day! Beats the pants off my old bubble magus curve 7
  • Great skimmer, Great price By Larry on 12/30/2014

    I bought this skimmer to upgrade from my SCAquariums SC-250. WOW! What a difference! I guess this is my first "real" skimmer and I have to say - you get what you pay for. I looked at every skimmer on the market and decided on the SKIMZ SM163 because it was the only one that would fit my sump and give me the tank rating I needed. I feel - for the price - I got more skimmer for my money as well, compared to other brands. Skimmer is built very well. Easy to put together - mine did come with instructions, but if you've ever seen a skimmer, you know how it goes together. After 2 days it started producing more foam than I ever saw out of my cheap, knock-off skimmers. It is completely silent-can't even tell it is running without looking at it. The "gate" water level adjustment is awesome-with the outlet on the bottom of the skimmer, there are 0 micro bubbles to deal with. And the added fine adjustment on the silencer lets you fine tune the skimmer. The DC pump is a nice feature, but I really don't use it-I just run it on full power, but it adds another level of adjustment as well. If you are considering a SKIMZ skimmer - DO IT!
  • So far so good - pulling skimmate after 2 days By Anthony on 12/18/2014

    This skimmer is well built and very quiet. It started pulling skimmate after just 2 days. So far I'd definitely recommend. Of course in a couple of months I'll update this.

    One important thing to note, the description says, 'Foot Print: 7.4” x 7.4”,' though technically true, the decorative scalloped ring (not sure what else to call it) toward the top of the skimmer is actually wider than the base. I'd guess closer to 8"x8". So if you are putting this in a REALLY tight skimmer compartment in your sump where a tenth of an inch makes a difference, you'll want to take that into consideration.
