Stay away! By Jay on 4/24/2018Jay wouldn't recommend this product to a friendThe worst skimmer ever! First of all its loud, if noise is important to you then stay away from this one. It was recommended to me by an employee at BRS and boy were they wrong. Sound measurements are at 63 db!! Quiet it is not. It's in the living room and if it's on you can hear it over the TV..After numerous calls they direct me to coralvue who's answer was the impeller must be broken. I sent pictures of a perfect impeller, their answer... we'll send you another impeller. I didn't even mention it never broke it, 3 weeks of running and non stop overflowing bubbles, they never stopped no matter how low or high it sat in the sump. Lesson learned, now I'm stuck with this $200 paper weight.
Newer model is nowhere near as good as the older model By Clay on 4/19/2018Clay wouldn't recommend this product to a friendMan, RO used to be really good. I had an older model of the Classic 110INT and it was the best skimmer I had ever owned. This newer model with the newer pump is nowhere near as good. The older model was SILENT fresh out of the box and pulled some nasty skimmate right away. I'm not sure what they did to the pump, but mine was LOUD! My tank is in the farthest room from my living room, but I could hear it loud and clear. The noise level did not improve over the course of a week. Also, the older pump used to mount to the side and sit on the bottom of the sump. The newer pump hangs on the side, putting the skimmer off balance. Reef Octopus seriously dropped the ball on this newer model and should probably fire the engineer that came up with the idea to essentially hang the pump on the side of the skimmer body. What a bummer.
Incorrectly Sized Piping, Unusable Out of the Box By Nicholas on 12/25/2017Nicholas wouldn't recommend this product to a friendBased on the build quality and the other reviews, I assume that this is actually a pretty good skimmer. I can't tell, though, because the pipe that's supposed to connect the skimmer to the gate valve wasn't sized correctly. It fits into the gate valve as it should, but won't fit into the output from the skimmer no matter what I do. I can likely file it down to get it to fit, but if I'm spending a couple hundred dollars on something, I don't think that it's too much to ask that I don't have to spend additional time just to give it the functionality it's supposed to have out of the box. Quality control was lacking to ensure that all of the piping was sized correctly so that it can work out of the box. Buyer beware.
Worked great By Richard on 11/20/2017Richard would recommend this product to a friendBought this for a 65 gal heavily stocked mixed reef. Worked like a charm. Liked it so much I bought another reef octopus, a 150int, for the 120 gal i'm setting up now.
perfectttt for a 75g sps tank By angel h. on 5/18/2017angel h. would recommend this product to a friendnot complaint at all,excellent performance... perfect fit in my trigger sump, silent runnig operation, good price and excelent warranty terms...out there, nothing think about that...
Great product. By Reggie on 1/31/2017Reggie would recommend this product to a friendGreat product but the clear air canister is making a loud winding sound, I hope It goes away after the break in period.
Great Value By tdmartin on 1/9/2017tdmartin would recommend this product to a friendThis is a replacement for an Eshopps psk 100 on a 65 Gal in a 20 High sump. Some people complained that it was sensitive to tune. I had no issues what so ever. Easy to tune for me. My old Eshoops was a pain. I ended up modifying the design of that one. Also some said that it has a balance issue. It does. when empty it will tip over. HOWEVER, once full and running the weight of the water in the column stabilizes the unit and it is fine. A base plate would solve the issue completely. Not sure why they did not add that, but bottom line it is just not an issue. Produces great skimate. I have only had it a month, so I can't say anything about reliability. So far this counts as one of the best purchases I have made to date.
Happy with This Reactor By Bill on 9/9/2016Bill would recommend this product to a friendI've already been running the 6" version of this skimmer and was very happy. I had a smaller tank (40 gallon) that needed an ungraded skimmer and went with this smaller version. So far it has been working well but I wish I went with the larger skimmer as this one seems to be a little harder to "set." I'm happy with the pump and the skimmer product and it does a good job of sucking out the junk. You can't go wrong with this.
Unit to big for sump By JimA on 3/29/2016JimA wouldn't recommend this product to a friendIt is so big it will not fit in the sump I am not sure what to do with it
Loved until pump died By Ryan on 3/20/2016Ryan wouldn't recommend this product to a friendAbsolutely great skimmate produced after just a few days. Short break in period. I haven't even owned this one month and the pump stopped working. Hope BRS will replace.
Excellent By Xecros on 3/14/2016Xecros would recommend this product to a friendI just recently bought this Skimmer in preparation for building my tank. I did a lot of review readings, and comparisons to other makes and models. Probably a good solid 48 hours worth of research.
For my tank size (55 gallon), for the price, this skimmer is hands down, the best you can get.
Having said that, there is a problem with balance, (stability). Fully assembled, without any water, not running, it will stand on it's own. But, it will easily tip over with the slightest pressure. If your going to remove the skimmer cup for cleaning, use 2 hands! One hand to hold the skimmer in place, the other hand to pull off the skimmer cup.
My plan to overcome/fix this annoyance, is to silicone the damn thing in place. I plan to use 3 or for dabs of silicone, and silicone it in place. Kinda like spot welding, I'll be spot siliconing the bottom of the skimmer to the sump itself.
Great Product By crabs_mcjones on 3/5/2016crabs_mcjones would recommend this product to a friendI upgraded to this unit from the Seaclone 100 and have noticed a night and day difference. This skimmer works excellent and is a grwat buy at a great price.
What is the recommended sump water level for this skimmer?
This skimmer will work well in 7"-9" of water. Feel free to let us know if you have any further questions!
Will this work on a 90 gal with 20 gal sump?
This could work with a very light bio-load not too many fish, most likely around 4-5 and a lite feeding. Feel free to let us know if you have any further questions!
Could the unit be supplied with a water source plumbed into the venturi inlet instead of through standing water from the sump? I'm curious if I could use it in my aquaponic garden. Many thanks !!
If you are looking for a skimmer that has a feed for the water intake we would suggest looking into a recirculating skimmer since they require some type of source to be fed into the skimmer from another pump, or overflow. By plumbing a source water into the intake of the venturi you may change the characteristics of how the pump runs and pulls air.
Just an FYI the protein skimmers we carry are designed to work with saltwater only and will not be effective in freshwater.
Have a smaller sump with a 9x7 sump chamber. Is there any orientation that will allow this skimmer to fit?
Unfortunately with those dimensions it would not fit in any orientation.
Will this be good for my 55g tank?
What size compartment in my sump/refugium is needed for this? I plan on having it sit in the 1st stage were the water input is, and the output from this would be going into the refugium (2nd stage) of the sump/fuge
The footprint of the skimmer is about 11x7 so you will want to make sure that you have atleast that much space for it.
Hi guys. Sorry if this is in a previously asked question, but the "view all questions" link is broken. I just installed my new Reef Octopus NWB110 and I'm not sure how to set the gate valve. The manufacturers instructions were kind of unclear about that. I initially set it so that the foam reaches the very top before it falls into the collection cup. Is that correct? What is the ideal way to set the gate valve? Thanks for the help.
I apologize for the broken "Questions" feature, I'll have our web team look into it if they are not already aware of the issue.
For the initial water level setting I would set it at the wavy line on the skimmer body and adjust from there as the skimmer breaks in and you can determine how the skimmer behaves in your particular set up. If you are not getting any skimmate in the cup after 24 hours you can slowly raise the water level in the skimmer until you do at which point you can make fine adjustments to get the desired amount of water/skimmate in the cup. Some people like to skim "wet" (lighter colored liquid) while others like to skim dry (darker colored liquid).
I hope this helps!
Have a great day :)
