  • Great skimmer By on 3/3/2017

    I currently have this skimmer running as the only equipment on a 14g Rubbermaid frag tank and so far it works well for the money. Yes the plastic feels cheap and somewhat flimsy and the pump only pushes about ~50gph and it puts out some air bubbles, but what do you expect for <$50? All in all its a pretty decent skimmer for the size and price. My favorite thing about this skimmer is that it's basically a miniaturized version of some of Reef Octopus' larger hob skimmers so if you're used to those operation and setup is basically the same.

    The only complaints I have are first that the collection cup fits much more snugly than the rest of the fittings, so much so that you pull the skimmer apart trying to empty the cup. Conversely the flow control is too loose so bumping it the wrong way can throw off the water level. Basically you HAVE to use a skimmate locker so as not to disturb the unit itself, but a simple shot glass placed under the spout lets you dump the skimmate without ever having to touch the cup. The second issue is that the output spout is above water level for some reason, so I added a small cpvc elbow to the spout so it empties below water level. This reduces splashing and a lot of the micro bubbles.

    Overall this is an adorable and functional budget skimmer for smaller tanks, and one of the few true minature skimmers out there.
  • Airbubbles By on 12/17/2016

    I find from my experience with product. Unit produces too many microbubbles. No matter how you dial it. And that it skims more on the wet side. You get what you pay for.
  • Good skimmer for nano tank By on 4/18/2016

    This is the second one I have purchased. I have a 23g bow front. After sand and rocks, I hold about 18 gallons. The only reason I replaced it, was because I left reefing for a year and lost some parts. I could have ordered replacement parts, but after shipping cost over half of a new one.
  • Woorks well By on 3/11/2016

    Works well, a little noisy but my tank isn't in the TV room so not a problem for me but may be for someone else
  • Fantastic By on 2/1/2016

    I needed something small and cheap for my quarantine tank. I ended up going with this and it's amazing, I've had several skimmers rated for 50-60 gallons and this thing puts them all to shame. You just have to be careful with it as it's made of cheap thin plastic, but that's to be expected with how much it costs. Overall this thing is great, great bang for your buck.

    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 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 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 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 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.
