This will need the water level to be around 2-3 inches below the rim for the siphon to start. As long as the water int eh sump is high enough to keep the intake and output submerged. Feel free to let us know if you have any further questions!
This will use metric tubing however most likely you will want to measure the barb that attaches and find soft tubing in either 1/4" inside diameter or possibly you may need 3/8". Ideally you will want to check first on the unit and see if your local hardware store has soft tubing measured by inside diameter. Feel free to let us know if you have any further questions!
This will hang 12.6" down from the top rim of the tank. Feel free to let us know if you have any further questions!
If you have a sump you wouldn't want one of the HOB back versions, just the regular in sump versions. The HOB systems are designed for sump-less systems and require the water level to be near the rim of the tank its sitting on, because sumps have much lower water levels a HOB skimmer would end up out of water in a typical sump.

Best HOB Skimmer By seahorseslave on 1/23/2017seahorseslave would recommend this product to a friendI have had reef tanks and seahorse tanks for over 20 years. I have tried just about every HOB skimmer past and present. I LOVE the bh-90 or now the classic 90. I breed seahorses and they are messy!!! This skimmer works perfect. If you can't have or don't want a sump, there is finally a skimmer that works just as well as an in sump skimmer. I do have in sump skimmers (SWC 160 and SWC 120) This works just as well. You will not be sorry.
Best HOB skimmer I have tried By Chris on 12/6/2016Chris would recommend this product to a friendI generally don't like HOB skimmers and prefer in-sump designs...but this unit is tough to complain about IMO. I'm running this on a 65 gallon reef for about 6 months now and it has been absolutely no trouble (no crazy noises, no leaks/spills, etc.) and collects a lot of skimmate.
It's a bit finicky with the adjustment when new (like many skimmers), but after a few weeks it really settled down and became very consistent. I originally planned to plumb the fitting on the collection cup to a drain or large container to protect against overflows, but the skimmer has proved so consistent and reliable I have not bothered. As with many skimmers...large water changes or certain foods (chunks of fresh seafood for the anemone for example) can make it go a bit nuts temporarily so I just open the adjustment pipe beforehand and then close it down again a few hours later once things have had a chance to settle back down.
Also (as with any HOB I have used) adjustment will be a bit sensitive to your tank water level so best to have an ATO system that keeps your tank water level consistent.
Works well. Wish it came in Red. By Airric on 10/19/2016Airric would recommend this product to a friendFrom a functionality stand point this skims perfectly and doesn't create micro bubbles. It is not silent, but by no means is it "noisy".
Set up is easy. Pulls water from the surface which is a great design. Sponges keep the microbubbles away. You can run a hose from the collection cup into a bucket - all skimmers need this.
Improvements? I wanted it to have red accents like most Reef Octopus skimmers. Wish the black sponges looked a little better.
Great skimmer once you get it going By Jeff on 6/23/2016Jeff would recommend this product to a friendThis skimmer is really great just like the rest of the reviews say. Cleans very well once you get it going. Every video and even the instructions state to pinch the air line then plug it in to get it going and then once all the air is out let it go and poof the thing works....well I found a better way that worked for me, take the line and close it off with the top of your thumb while holing the line horizontal while you fill the chamber. This way the line fills as you fill the chamber, no air. Turn it on and you can pretty much let it go and the skimmer is off to the races doing what it does best.
For reference this is my first skimmer/saltwater setup and so far love it!
A solid choice By Garrick on 6/4/2016Garrick would recommend this product to a friendIt does take some adjusting to get it dialed in to the proper levels for air and water, but within a day it was pulling out some serious gunk. It's also quieter than the fans on my LED lights.
the worse spent money By angel on 3/28/2016angel wouldn't recommend this product to a friendtoo complicated to adjust, super unstable, overflow problems, exes micro bubbles if you try to havea little wet skimmate.. brings a hole in the top of the elbo 90 degree return that splashing all around, if you replace the sock gets out a lot of bubbles and takes days to start to get something ... very bad !!!! if you want to be happy, stay away from this piece of junk
Hands down, best HOB on the market By Brian on 3/17/2016Brian would recommend this product to a friendI was running a Reef Octopus 1000 classic on my wife's seahorse tank, and it just wasn't pulling a lot of skimmate out. Swapped it out with this bad boy, and I'm emptying the cup every 3 days or so. Super job at keeping nitrates down in the tank, right around 5 ppm or so. Anyone who knows how difficult that is for a seahorse tank should be VERY impressed with how well this skimmer functions.
This thing is better than free ice cream By The Nitrate King on 11/24/2015The Nitrate King would recommend this product to a friendMy 65 gallon was mucky. This very quiet and extremely efficient skimmer picks up the darkest skim crud ever. Collect them all!!!
Excellent By NewtoReefing on 8/30/2015NewtoReefing would recommend this product to a friendReplaced my Remora HOB with this beast. I am battling an outbreak of hair algae that will not subside despite all the measures I have tried. Decided to replace my skimmer.
Absolutely love the amount of skimmate produced. The break in period was literally 4 days. The skimmer is quieter than my prior skimmer. I ran both skimmers for 1 week just to compare. This out performed the Remora 5:1. Definitely recommend.
great skimmer By JD on 8/22/2015JD would recommend this product to a friend!st hob skimmer - worked great from the start
Works well By Shawn O on 7/13/2015Shawn O would recommend this product to a friendThis skimmer works pretty well. As it's my first and only skimmer, I have nothing to compare it to, so.... I'm giving it a 5 because it does pull out crud from the water without making a lot of noise.. It only took about 3 days to break in. If I set it just right, I get dark skimmate. If I set it just a hair either way I get slightly tinted water or nothing but crud inside the cone. I'm running this in a 55 FOWLR with 6 fish. I think it would pull out more crud if I took my aquaclear 70 offline.
Fantastic By Tim dogg on 6/6/2015Tim dogg would recommend this product to a friendI have this unit on another tank and I love it. The best HOB skimmer out there. BRS had the best price and quickest delivery. Customer for life
