  • Great skimmer By Felix on 10/9/2017

    Fits perfectly in my trigger 26 sump. Put together rather quick and starter pillín skimm right away.
  • Excellent Customer Support By Ken on 10/3/2017

    I believe a product like this is only as good as the customer support staff and how well they assst you with problems. I had a defective pump on my 150SSS, called their support number and received immediate, action and was back in business. They were professional and worked hard to take care of my problem quickly. They have a life time customer now!
  • Small footprint, Strong skimming By Josh on 7/27/2017

    I love it, small footprint strong skimming and basically silent
  • A+ Skimmer By Jeb Brosh on 2/14/2017

    Ordered sunday night and the skimmer arrived on thursday. Easy to put together. ran it in freshwater for just a bit to clean it off and put it in my sump that night. the next morning i already had a little bit of green skim. The thing is next to silent, its actually quieter than my overflows so you cant even hear it unless i have my stand doors open. worked/works perfectly and looks great. Writing this review almost a week after install and everything still works. skims better after initial break in
  • Excellent skimmer for the price and size By Rusty on 2/13/2017

    I run this in my Trigger cube sump under my 93g cube and it works like a champ. Easy to setup and maintain.
  • A GREAT SKIMMER FOR THE MONEY By Charlie on 8/27/2016

    I'm very happy with this purchase. Small footprint, good performance, quiet, easy to adjust and maintain. I would recommend this skimmer and I would buy it again.
  • 150 sss for sps 75g By johann garcia on 7/18/2016

    A W S O M E E E E !!!! Works fine from the first instant in my break-in needed...dead silence, big collection cup, small footprint, .... for the price and quality...nothing to think about it!!! 100% high recommended.
  • Nice skimmer so far. By Sppf121 on 7/13/2016

    I looked at many different skimmers and do to sump size decided on this one. So far I am very happy with it. It's pretty quiet. Fits well in my Red Sea reefer 250 sump with room for a heater, apex probes, and the ability to easily change my filter socks. I would recomend this skimmer.
  • Great so far! By david s on 7/3/2016

    Great skimmer very low footprint easy to tune and seals great without a locking mechanism. Already skimming loads more than my previous skimmer only a week in. Only complaint is the lid doesn't lock in so it becomes dislodged by the heavy amount of bubbles coming through the neck. Easily solved by sticking a full water bottle on top
  • Great skimmer By Gee on 6/27/2016

    Been running this for about 5 months on my 90g It is a compact great skimmer. Very satisfied would buy it again!

Product Questions

Do you have to adjust this skimmer? Or do you just set it up and go ?
Question by: Travis on May 8, 2016 8:41:00 PM
Great question.
Skimmers will always need to be adjusted to fit your system size and bio load. This is done with the stand pipe adjustment, air intake adjustment and overall height.

Can I fit reef oct 150sss 6" inside a emerald 26 trigger sump
Question by: Tony on Mar 31, 2016 1:46:00 PM
Great question!
With the Skimmer having a footprint of 7.3"x9.5" and this will fit fine in the sump area of the emerald 26 which has dimensions of 8.25" x 10". Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 5, 2016 12:19:00 PM
I'm trying to decide between the 150sss and the 110sss for a 65-gallon sps tank. I'm confused because the BRS suggestions on the 150sss shows 65-gallon heavy bioload but in the Q&A section for the 150sss it says 110-gallon for heavy bioload. Please advise, thanks!
Question by: Ryan on Dec 17, 2016 10:55:00 AM
Great question! It looks like we answered that question prior to putting the skimmer to the test and coming up with our listed recommendations. The recommendations you see in the product description are a more accurate representation. :-)
Answer by: Randy (Admin) on Dec 22, 2016 5:19:00 PM
Ok. I have a DSA Neo 105 (100 gallon) and an emerald 34 sump. Thank is mostly sps and some lps but only around 15 3 inch corals. I'm Essentially an ultra low nutrient system and dose NoPOx.
I see great reviews on this skimmer and just can't swing the cash for a Nyos or any $450 skimmer. Size wise I believe the RO 150 is capable is it really as good as the reviews and the bubbles as fine as I read about? Or is there a better choice up to $350 ish range
Question by: sean benson on Apr 14, 2016 5:10:00 PM
Great question!
We have had great luck with the Classic 150sss. It is a very small footprint and does perform as well as the reviews say! Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 19, 2016 12:15:00 PM
Will any of the Reef Octopus auto neck cleaners fit the 150SSS skimmer?
Question by: Charlie on Aug 14, 2016 4:15:00 PM
Great question! According to the product specs from Reef Octopus, the ANC 150 will work with the Classic 150sss. If we can be of further assistance, please let us know. Have a great day and happy reefing!
Answer by: Zack (Admin) on Aug 16, 2016 2:32:00 PM
Your light/medium/heavy recommendations on the 110 version of this are super helpful. Any reason you haven't done the same fo this skimmer? (heck, there is no BRS recommendation on this one at all)
Question by: John Donahue on May 14, 2016 10:33:00 PM
Great question!
These have been recently redesigned and not had a chance to fully complete the testing. On these skimmers we recommend 200 light bio load, 150 medium, closer to 110 with heavy. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on May 19, 2016 1:47:00 PM
Occasionally I have to service the pumps for my tank to remove calcium deposits. Is access available to the moving parts of the motor? Easy access?
Question by: Ken Rees on Apr 19, 2016 5:44:00 PM
Great question!
The pump is fairly easy to remove by removing the skimmer body and dismounting the pump. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 19, 2016 6:17:00 PM
I have an Eshops RS-75 sump on a 75 gallon aquarium. The skimmer section is 7.5 x 9.5 The sump and skimmer will be under the stand. Will this fit or do I need to go with the 110SSS to be able to remove it from the sump for cleaning?
Question by: Jim on Apr 20, 2016 3:46:00 AM
Great question!
The 150sss would be just a little too large for the sump. We recommend the 110SSS for easy removal and cleaning. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 26, 2016 1:30:00 PM
What is the recommended water height for this skimmer?
Question by: Josh on Mar 14, 2016 10:31:00 AM
Great question!
This will work with 7-9" of water. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 15, 2016 3:53:00 PM
I recently ordered the classic 150 sss for my 75 gallon heavily stocked tank running a emerald 26 sump. Is this skimmer to big for this tank setup or do you recommend I go with a different skimmer. Thanks!
Question by: Steve on Jun 1, 2016 9:16:00 AM
Great question!
This skimmer is oversized until the bio-load of the tank will catch up. Once tuned correctly this skimmer will not have any issues on a tank of your size.
