Overflow with hang on back skimmer is an inherent risk and will need to be set up under observation for the first several hours and possibly even weeks during break in. You essentially will move the o-ring on the collection cup to set the cup at its highest level. Once a day for the first week you can slowly lower the cup until the skimate is forming. Feel free to let us know if you have any further questions!
Also I have a 75 gallon lightly stocked only two medium size fish. Would this skimmer be a good choice?

Awesome BUY By Chris on 1/3/2017Chris would recommend this product to a friendAfter five or so years, many diy and store bought purchases (from tanks to Skimmers and sumps to Refugiums, this has been my best improvement yet. I started with a small Tunze 9004 in a 20 gallon Long and kept it when i moved to a 38 gallon and a ten gallon sump (scrapped the Fuge).
Getting ready to buy a cuboid shaped frameless/rimless and build a stand to house my sump and ATO tank. This is one of the few improvements/changes before the tank comes. VERY PLEASED!!
Easy to set up, allow for break in and see how the foam builds! Incredible performance, VERY quiet even compared to a tunze 9004. Much more powerful pump and a good sized collection cup. Should last a long time!
MAKE SURE YOU INSPECT FOR IMPERFECTIONS FROM THE CASTING.. I HAD A FEW SPOTS TO KNOCK OFF AND CLEAN OUT FOR OPTIMAL PERFORMANCE.. +A1
Good By Darryl on 7/21/2016Darryl wouldn't recommend this product to a friendBought this for my 30 reef as a temporary skimmer, It works very nice, think I will keep it!
You must keep the cup above the overflow hole and correctly prime it for first run and then it runs by itself.
Great Skimmer By Cody on 3/6/2015Cody would recommend this product to a friendPros: Works awesome, very quiet
Cons: Kind of bulky for a hang on the back model, slight eye sore in the tank
Notes: Possibly a common error, but when starting this skimmer for the firs time, leave the cache can off, i had mine adjusted to the very bottom and water kept spilling over onto the floor. Place the cache can slowly moving it down further until you have no over flow. Overall, great product!!!
Awesome Quiet Skimmer By Mike on 12/26/2014Mike would recommend this product to a friendGot this skimmer for Christmas! As soon as I turned it on it went crazy because I just upgraded and decided I really need a skimmer. Went from a 10 G to a 20L and have this on my 20L, it pulled decent yellowish/greenish skimmate as soon as I turned it on. Compared to the 10, the fish tank is lightly stocked (pair of clowns, six line wrasse, cleaner shrimp) and basically did a 50% water change when adding this skimmer. It is very quiet and still in the break in period so I hope the skimmate gets dark as said. I gave it 5 stars because it was easily assembled although the directions weren't that helpful but its well built and QUIET.
Reef Octopus BH100 By Guy on 5/22/2014Guy would recommend this product to a friendWorks great. Just let it break-in and fine tune it. Easy, easy, easy. Performs great and super quiet.
Great Skimmer By Lionel on 4/10/2014Lionel would recommend this product to a friendI'll save you hours of research. This is a well built, relatively quiet skimmer. I was looking for a skimmer for my 50 gal breeder and I'm very happy with Reef Octopus's products. My only regret is not going with the 1000 or 2000, mostly because of the external mounted pump and 50 gallons seems to be the biggest tank I would put this on.
Overall, a great product that does what it says.
Awesome Skimmer! By Adam on 3/28/2014Adam would recommend this product to a friendA great skimmer for someone who is still new to the hobby. I've only been keeping saltwater tanks for a little over a year and this is one of my best purchases, next to an RO/DI system. It took a little over 48 hours for it to break in and start producing a light skimmate. After a week I had some nice, dark skimmate being pulled from my tank.
The only negatives to this skimmer are the directions and the in tank pump. Youtube quickly solved the directions problem and the in tank pump does take up some room in my 29gal tank, but the way the pump is set up it skims the top of my water which I really like! The only other downfall is the open side of the skimmer leading to the return. This just adds a little more to the salt creep and evaporation - but that's what top off RO/DI water is always for.
Even with the few downfalls I still give this skimmer a 5/5 because of the quality build of the skimmer and how it functions so quietly. My old Coralife super skimmer was extremely loud and this skimmer is the complete opposite.
My first real skimmer By N. Clark on 3/7/2014N. Clark would recommend this product to a friendAfter spending quite a few months researching skimmers for my new 45gal tank it came down to two models; the Reef Octopus and the Aquamaxx. After talking to some people on a few reefer forums, seeing a huge one up close at my local zoo, and chatting with a few LFS employees I ended up with this one. It was pretty easy to put together even though the instructions are a little useless.
Once I got her up and running she started pulling things out of the water right away. I was having to empty the cup two-three times a day for the first few days. Now that its been about a week or so it's down to every other day or so.
It's a very quiet skimmer. Just a little bit of noise when it first starts up. I think my Marineland filter makes a racket compaired to it.
All in all though I am very happy with it!
Excellent By Keyser Soze on 3/7/2014Keyser Soze would recommend this product to a friendI'm very pleased with this skimmer. It's well built, works well, and is quiet as a mouse. It comes mostly put together, just look at the diagram to complete the assembly. There is no priming of the pump, no bubbles in the tank, or any surprises involved. Just plug and play.
The only negative is the supposed "surface skimmer" intake is too short to reach the surface (for me). I think there have been several versions of this skimmer and they add small improvements with each version.
Works as stated By Eric on 1/1/2014Eric would recommend this product to a friendThe directions suck, the skimmer works great , if I were to do it again I would get the BH1000 model instead because it has the pump outside of the tank. I knew this when I got it but was in a hurry. My water is crystal clear in a 40 gallon breeder tank with a Greenspotted pufferfish.
Good Quality - Quiet Operation By Mark on 12/29/2013Mark would recommend this product to a friendGood Skimmer for a good price.
Would Buy Again By Brandy Anderson on 11/29/2013Brandy Anderson would recommend this product to a friendI've had this skimmer for about 4 years, and it's still working great. Only complaint is that the rubber band holding the collection cup in place will wear out eventually and you'll have to replace it, but that's not a big deal compared to the great value of this product.
