This should have no issue fitting in the 9" x 8" skimmer area in the sump. Feel free to let us know if you have any further questions!
1 coral beauty
2 small wrasses
And a moderate amount of coral and inverts.
The SM123 would be fairly small on a system of your size. We would recommend the SN143 as a great alternative.
This skimmer has a footprint of L 6.41"x W 7.36" x H 19.29" and will not be able to fit in a 4.5" area. Feel free to let us know if you have any further questions!
Have a great day!
This will save the most recent setting. Feel free to let us know if you have any further questions!
between 7" and 9".
Skimz SN123 Monzter Mini Protein Skimmer
The SN series of protein skimmers are ideal for tanks that do not have a lot of space in the sump available. The footprint is under 6.5" x 7.5" which makes it very easy to fit in almost all locations and sump types.
Updated VSC1.2 DC Controllable Pump
All Skims SN123 skimmers now come with the updated VSC1.2 controllable DC powered pump. With multiple power modes, you now have full control over the amount of water and air that are flowing into your skimmer. The updated pump has had the electronic control devices integrated into the controller instead of the motor block like most other DC pumps. That now eliminated the chance of heat or water coming into contact with the sensitive parts of the pump, leading to a much longer life.

Compact but low quality By Eric on 6/9/2017Eric wouldn't recommend this product to a friendThis was basically the only good skimmer option for the sump in my Red Sea Reefer Nano. Design wise, I really like this skimmer. Performance was pretty solid too. Build wise, not so great. Water level adjustment knob seems very flimsy. The pump on mine died after 13 months, one month past the warranty. Took it apart, cleaned it, no dice, motor is likely shot. $109 to replace the pump. Unfortunately there are not a lot of options at this size/footprint. Wish Vertex made a nano sized cone skimmer.
The D@^^ Collection cup..... By Chad on 2/17/2017Chad would recommend this product to a friendBreaks in really fast and produces a good skim. Is incredibly easy to adjust in multiple ways with it's DC pump and fine adjustment gate. The biggest failure it has is the total failure in engineering of the collection cup and skimmer neck. I broke it the second day I had it but luckily BRS service is great and second day air shipped me a new one. They said it's a known problem due to tolerances in production. This is understandable but they should have anticipated such for how much they cost.
Has a break in By Robert on 2/16/2017Robert would recommend this product to a friendThe first few days the skimmer had a extremely loud noise. The pump was making an obnoxious humming noise. About 6 days passed and I came home to a completely silent skimmer! This skimmer is literally silent! My power heads are louder than this thing! The skimmers performance is great but has a crazy break in. If you can deal with a noisy skimmer for a week, this is a great choice!
Spotty reliability By Darren on 2/2/2017Darren wouldn't recommend this product to a friendThis skimmer presents a very good value for the money at first as it produces pretty good skim. After several months of use I have noticed some irregularities and loud noises coming from the pump. After a deep vinegar soak I managed to get it to run fine again but I had to repeat this numerous times throughout my time owning it. If you look up Skimz skimmers online you will see that numerous people had very similar issues.
Good skimmer when pump works! By Renee on 1/5/2017Renee wouldn't recommend this product to a friendSkimmer worked well once I figured out the best adjustment for my system. Unfortunately the pump started messing up over the past couple of months. It will seem to run fine but when paused to feed, it will not start back up. After taking it apart, cleaning and putting it back together, it won't even start up now. And, of course, the warranty was up in October! Noticed they have an improved version for sale now.
Silent By CXK03fishtanks on 6/26/2016CXK03fishtanks would recommend this product to a friendAt first when I got this skimmer, it made a terrible loud noise, and could be heard the room over. However, once BRS replaced the defective pump, it was dead silent. You can only hear the pump if all the other equipment is turned off. This skimmer works great, and removes a lot from the water. The only bad thing I have to say, is that the skimmer cup is impossible to come off. This just makes it a little harder to clean.
good skimmer but... By jeremy on 6/19/2016jeremy wouldn't recommend this product to a friendJust got the skimmer last week ans BRS helped me set it up and get it running. Seems to get a good wet skim after just the first few days. Now the bad...... The seal that hold the the cup on is so tight and hard to get in and out I have broken the gate control knob twice now. Have to call them again tomorrow. and get this fixed. I did use a small about of tank friendly lube but it just too big and it take the force of 1000 men to get the skimmer cup off. Makes me not want to even keep this skimmer because of that. Other than that seems okay, directions are not very good and don't offer much help.
Skims Like a Beast By Lukas on 6/14/2016Lukas would recommend this product to a friendThis thing performs excellently and has many features you would normally need to pay a premium for. This having been said there are a couple of design flaws. The skimmer cup is tight which is a good thing, but this thing is insanely tight. Without lubrication of some kind it is almost impossible to get off without at least feeling like you're going to break it. The air silencer is attached to the skimmer rather flimsily and it's position next to the ridiculously tight skimmer cup pretty much ensures you are going to bump it, strip the screw out and end up with a loose air silencer. Still a great skimmer otherwise and I will buy Skimz skimmers in the future.
Hard to beat for the price By Brian on 6/8/2016Brian would recommend this product to a friendI have been using Skimz protein skimmers for about 4 years now and they just plain work. Skimz products are well built, and in my opinion, extremely tough to beat at their price point.
Awesome By Joshua E on 4/30/2016Joshua E would recommend this product to a friendGreat skimmer with quick break-in time. I agree with others that the skimmer neck could use some better engineering for easier taking apart and cleaning. Very quiet.
A+ job by Skimz! By Adam on 3/9/2016Adam would recommend this product to a friendI did quite a bit of research before buying a new skimmer for my 20 long. I wanted something that was able to handle a 75 gallon tank when I upgrade down the road. This skimmer seemed like a good value. Boy was this purchase a great decision! My skimmer has been running on my tank for about a month now and I have nothing but good things to say about it. It was super easy to break in and adjust to a perfect dry skim. The build quality is great for the price, and the controllable quiet dc pump is the cherry on top! My only complaint is that the collection cup can be hard to remove. Other than that minor detail, this is the best skimmer I've owned...not that it had much competition with my coralife skimmer :)
SN123 is good skimmer By BobbyB323 on 1/20/2016BobbyB323 would recommend this product to a friendSkims well. Bit tricky to dial in because there's three adjustments; pump, air and water level. Break in according to instructions. After break in recommend air half open (1-1/2 turns from closed), pump at speed 6 of 8 and adjust water level to bottom of cup. Presto!
