  • Octopus skimmer By Robert on 11/13/2016

    Own this for 3 years and it's absolutely a beast!
  • amazing skimmer By dino on 2/4/2016

    I got this skimmer with a used tank i purchased and im impressed. It skims like a beast. Going from a nwb110 on my 60g to this 200 on my 160. Im in love with this skimmer. And it no louder than anything else in my tank. I can barely hear it
  • Awsome By Brian R on 1/1/2016

    This is an awsome skimmer!! Made very well and once you get it broke in and dialed in I've never had to re adjust it.
  • Awesome skimmer 1 year and counting By AZ Big John on 4/2/2015

    I have only owned Reef Octopus skimmers, so I may be biased, but this beast is great. I cleaned and vinegared the entire setup at 6 months and a year, and it continues to impress me. In smaller tanks I had the 4: skimmer, and loved it, so when I bought my 155, I knew I would get another one.

    It is as big as they say, and a tight fit for me, but the skimmate I get makes it worth it. As for noise, I really don't think it is that noisey, but I have nothing to compare it to
  • Good skimmer By Mark on 1/14/2015

    I have owned the 4" 6" and now the 8" reef octopus int skimmers. They are quality made, affordable and skim like crazy!!! one of the only skimmers with gate valve in this price range.
  • Good Line of Skimmers for the Price By Chris on 7/22/2014

    I recently upgraded to the 8" after running the 4" for some time. I upgraded my tank and added biopellets so I wanted the larger sized skimmer. So far so good as i'm still breaking in now. Pump rattles a bit, but for me it's not a problem in my basement sump. Running this on about 110 gallons of system water.
  • Great skimmer By DC on 2/20/2014

    Great skimmer in my opinion. Started skimming yesterday and its already pulling out some skimmate.. Relatively quiet, easy to tweak.. Definitely need a decent size sump, i put mine in a 20 gallon long tank, that i partitioned. It has a pretty big foot print, and is pretty tall, but it fit nicely into my sump under a 75 gallon stand.

    I have fead some of the bad reviews on this skimmer, and have not personally run into any of the complaints., and i will say that my corals have noticed a difference already. I was not previously skimming in this tank, because i didnt really have any kind of bioload, but recently have been adding more livestock, and the skimmer is working as advertised well before the stated break in period.

    I would highly recommend this skimmer, even for a beginner
  • Good skimming but noisy By joseph on 12/9/2013

    The first year this skimmer was pretty quiet. Now that it is 13 months old, it has become noisy. Very noisy. I hope to find a quit one soon.
  • good loud skimer By Jason on 10/8/2013

    The skimmer works great the only problem I have with it is the noise. Ican hear the loud hum sound as soon as I het the top of the stairs. Think I want to upgrade the pump to quiet it down. If the skimmer wasnot this loud it would have 5 stars. I have it running on a 120 with a total water volume of about 140
  • Great skimmer By Jay on 9/18/2013

    I would like to begin with the dimensions of the skimmer they are spot on to what brs list and reef octopus has, in my case it turned out great because I went ahead and built the compartment for the skimmer on a 20 gallon long tank used as a sump. I have had the skimmer up and running about a month now and it is working really well. The one drawback I see is that some of the really fancy skimmers allow you to adjust the size of the bubbles along with the water level line. This skimmer allows only adjustment of the water level line which is fine by me since it is pulling the gunk out and it is not a top dollar skimmer but still worth every penny. Lastly I would comment on the noise of the skimmer. It is not the quietest thing in the world but it is in my living room so I don't have to sleep with it and in my case that is fine, I am not a noise junkie and my dog comfortably falls asleep next to my tank. With the cabinet closed I hear a hum and slight splashing sounds of water but this is not the deal breaker for me.
  • skims but noisy By trueopinion on 8/29/2013

    the skimmer is solid and skims great but the pump is bulky, cheap and very noisy
  • Reef Octopus NWB200 By Budman on 3/14/2013

    I switched skimmer and went from a SWC160 to Reef Octopus NWB200, I've had it 3 days now and its nowhere near as quiet as my old, still hasn't had a chance though to break in which they say in the instructions could take 3-4 week, Thats a long time for a skimmer to break in ,I have to say after the 3 days Im starting to see foam,that being said its been 3 days of not exporting nutrients.I hear a hum from it and I should of went with one that had a better pump.I will give it time to see if it quiets down and i will update this in a couple weeks

Product Questions

I was wondering if this skimmer would work in 4.5 inches of water? If not I would require a bigger sump but my space is limited to 32 inches long 15 inches deep.
Question by: Jerry on Feb 4, 2015 4:24:00 PM
Great Question Jerry! We would recommend sticking to as close to the manufacturers recommendations as possible (Recommended Sump Water Depth: 7.5"-8.5") for best results.

Hi, do these skimmers come with a wedge pipe or gate valve for adjustment? I see a gate valve in the picture here but I have seen pictures and reviews elsewhere showing a wedge pipe...
Question by: Ken on Sep 2, 2013 6:56:00 AM
Hi Ken,
They come with a gate valve. They used to come with a wedge pipe years ago but have been gate valves for quiet some time now.

Hello, what is the minimum sump size to properly house this skimmer?
Question by: Walter Maldonado on Nov 28, 2016 5:46:00 AM
Great question! The foot print of this skimmer is 14.6" x 9.8″. So you will need a sump large enough to accommodate that footprint. :-)
Answer by: Randy (Admin) on Nov 28, 2016 7:27:00 AM
trying to decide between this skimmer and the 202s in a 90 gallon with a medium load. any thoughts
Question by: Tom Lowers on May 23, 2017 8:35:00 AM
If you have the room for it, I would personally go for the 200INT. The space saving skimmers are always a bit of a compromise on performance in order to save space, and as long as that's not a limiting factor, you'll find it's easier to maintain the skimmer pump and you get more ideal performance from the classic skimmers with externally mounted pumps.

Hope this helps!

What are the differences between this model and the classic 202-s model?
Question by: Mark osborne on Mar 12, 2016 2:10:00 PM
Great question!
The difference will come down to foot print size. Both will be designed for 250-150 gallon systems. The 202-s has an internal pump while the 200int has an pump outside of the skimmer body. Feel free to let us know if you have any further questions!
