      Im getting conflicting answers....can I hang this on the back of my aquarium outside of the water* like larger HOB units?

      Bulk Reef Supply Hey Matt,
      The bracket itself attaches to the back rim of the aquarium but the skimmer body itself must be situated inside of the tank.

    • Great skimmer By Harsh on 3/27/2015

      Skimmer works great. Took one week to Break in good and now it's pulling out a lot of dark gunk
    • Works ok but... By ChuckD76 on 8/17/2014

      This is my first skimmer and I've been using it for a few weeks now.
      As others have said , Reef Octopus should have just saved the trees and not even included instructions if they were going to be as useless as the ones included. A few YouTube videos later and some careful squinting at the box and I figured it out though.
      One of the videos I watched was a general dialing in a skimmer video and from that I just set this one to where the top of the bubbles are just at where the collection cup attaches. By leaving it there the skimmer acts as a water level indicator for the tank and I just top off as needed.
      Skimmate has been a nice dark green/brown wirh a couple good chunks and a funky smell so I'm happy. Also, I've seen a slight reversal of some STN on a Montipora digitata since installing the skimmer.
      That being said, there is some bad:
      I have this on a pico reef, ~5 gallons, and for an in tank installation, for a tank this small, this skimmer is larger than I'd like it to be.
      Also, as others have noted, microbubbles are an issue so unless you can stick this in a sump or a HOB filter/refugium I'd seriously think about purchasing it. I did try a piece of filter floss as a bubble trap but over a short period of time the collection cup would flood so I gave up and just live with the bubbles for now.
      And finally, this skimmer is loud. Save yourself the headache and get a pill bottle and some spare airline tubing to make a silencer (thanks again, YouTube).
      Other than those few issues, this is turning into a nice little skimmer and I would definitly consider one if I had a sump to stick it in or was planning a custom AIO build and was making my own rear chamber.
    • OK for the money By Tom on 6/24/2014

      I bought this skimmer for my QT. The instructions are vague but if you have a general understanding of how a skimmer works, you should be ok.
      As for function: Maintaining water level is crucial if you want any type of consistency. The collection cup is very small so a skimate collection container should be considered. It will create micro bubbles so you may want to consider some type of bubble trap. But to solve all of these issues, I set the skimmer in hob refugium and once it broke in, besides emptying the collection container once a week. I didn't have any issues.
    • Overall terrible By Zak on 3/10/2014

      So i bought this for my IM tank and all i have had are problems. The air valve constantly clogs and some times air just stops flowing through i had a 100% better experience with an oceanic biocube skimmer; if you don't know about it, its the worlds tiniest skimmer powered by an air pump. Do Not get this product!
    • Great for a small Tank By Den on 1/24/2014

      I have this on my 10g I use as a frag tank. Started pulling skimmate almost immediately. Would have been 5 stars if it weren't for the directions that came with the unit. Pretty much useless. Had to find a you tube video to check how to set it up.
    • Good skimmer for small tank. By Geoff S. on 12/17/2013

      Within just a few hours it was pulling dark smimmate from my tank. I am using it on a 36 gallon bowfront which is larger thsn the recommended max tank size but I couldn't pass up on the price of it. I have been running it for almost 2 weeks at this point. It was a little tough to setup as the instructions were extremely vague but I got it figured out. It seems a bit overly sensitive to the water height - I am using it as a hob on my display tank. The size is just right to not be overly obtrusive in the tank yet not too small to be ineffective.
