The media could not be loaded. Great little skimmer, fits perfectly in the back of my AIO chamber and started skimming excess nutrients within 24 hours. A little tricky to adjust and get set where you want it but once you do, works great. Love the feed mode. The only thing I would change is where the collection cup could come off without detaching the airline, however there is a waste tube at the bottom of cup to make for easy emptying into a container. Also within 48 hours or so the micro bubbles were almost non existent. Video is within 24 hours of set up so still breaking in. Great skimmer and great customer service!

I waited a week to see how the skimmer performed to write a review. The thing works great and I have no complaints. The collection cup is on the smaller size but with the drain line you can easily leave it open to drain into another disposal container. Out of the box it was easy to assemble, but I have a few years experience in saltwater setups. The unit felt sturdy, the collection cup twist locks on top and has a drain line which is important if your running a large bio load. I'm using it on a 40 breeder with a 20 long sump. The skimmer won't hang on the side and as per the description it's for a rimless tank or sump. But I simply 3D printed a mount for it. I'm impressed with the little skimmer, cost comparison to other name brand skimmers, it does the same job at a fraction of the cost. The DC control means you can use it to help dial in the skimmer which makes tuning so much easier. I had it skimming well in just a few days, minimal break in time. I would recommend anyone needing a skimmer to go with this over the more expensive units. I'll update this review if anything else pops up down the road.

I ordered this for a clownfish tank I'm setting up. Seems pretty good quality. The box seems very professional. Usually with "Amazon specials" you get a random box that feels thrown together but the packaging was very neat and seemed well thought out. The skimmer itself seems like a solid construction, I wasn't worried about breaking it during assembly. I like that it came with a controllable DC pump which, for the price point, is uncommon for comparable skimmers. Tried it out on my main system, which although it's undersized for, it worked well and pulled out skimmate like it should. My sump has a rim but I was able to hand it off of one of the baffles and get it dialed in. The venturi from the pump to the collection cup seemed weird at first and I thought would make it a pain to clean the cup but there's a drain valve for the cup included so you can drain it easy without having to remove it. I might try and find a way to quick disconnect the hose in the future but for the price, that being my only gripe, I wont complain. An equivalent skimmer from the big name brand manufacturers would cost double what this one costs. The small form factor is pretty impressive as well.

I've been in the hobby for over 20years and never owned a skimmer, always felt they were unnecessary, but recently upgrade to a 100gal, and quickly realized I would never be able to fill the tank with live stock without a skimmer. This has been producing a lot of skimm and got my nitrates to 10ppm, from 40ppm. The only issue is how the pump attaches to the bottom, you just push it in and hope that it holds/stays.. I wish it fastened, as it has fallen out almost every time I'm removing the revisor to clean.. That said, it is working great.

The media could not be loaded. I own and operate a local youth facility. We have a 65 gallon reef located in the lobby area and some much larger tanks throughout the facility. We ordered this protein skimmer specifically for the compact size and controllable DC pump. This protein skimmer is replacing an old Coralife protein skimmer in a 65 gallon reef tank. Packaging - The protein skimmer was packaged extremely well and arrived promptly via Prime shipping. Provided in the packaging is the skimmer body, the collection cup and lid, waste valve, the pump, the controller, the power adapter, a soft air line, a soft waste disposal line, noise reduction feet, plastic mounting screws, and adjustable mounting bracket. All items were individually wrapped and packed firmly into a foam shock absorbing container that fit into the cardboard display box. Assembly - I had no issues in assembling the protein skimmer. It was pretty straightforward. The collection cup and lid simply twist locked into the skimmer body with secure tight seal. The pump output slid directly into the bottom of the skimmer body. The air line slid into the outlet located on the collection cup and connected directly to the intake of the pump. The waste line and valve connected to the outlet of the collection cup. The pump attached to the controller with a water resistant fitting that screwed firmly into place locking in an O ring to shield the connection from water. The power adapter plugged in directly to the top of the controller. I was very pleased with the ease of assembly. Installation - Upon removing the old protein skimmer, I was able to simply place the new skimmer into the chamber next to the systems roller mat. I was able to adjust the height of the water in the skimmer using the adjustable sliding mounting bracket that is attached to the skimmer body and then secured it in place with the plastic screws provided. The water outlet is adjustable with a simple turn of the skimmer body. I was able to adjust the amount of air coming into the pumps venturi by loosening a plastic screw located on the collection cup lid and moving the air intake slider slightly. The power of the pump is easily adjusted by pressing the intensity button with a power range of 1-10. The pumps power cable was plenty long enough to run the cabling to the far end of the aquarium cabinet where my other controllers are mounted. All that is left to do is simply plug it in. Installation was completed in under 10 minutes. Operation - The protein skimmer runs completely silent. I was surprised at how quiet it is. It is definitely better than the airy gurgling sound of my old protein skimmer. Tuning was simple. I run the skimmer at a power of 7 with full air and about a 10% decrease in water outlet from the skimmer body. The controller has a feed timer as well that is convenient especially if you were to have the pump located in the display (my skimmer is located in my sump). I was amazed to see that the skimmer had started producing dark skimmate so quickly. After the skimmer has had time to set in I will adjust the settings to run dry skimmate. Overall I am extremely happy with the operation of the skimmer! This protein skimmer is everything that I was looking for in a top quality product. Very pleased with my purchase! I highly recommend!

Excellent protein skimmer. You can't hear it at all. One of the best products that I have purchased. I not a fan of the unit being in the nano tank (20 gallons) but it works so good i have gotten used to it. I wouldn't mind getting something that hangs on the outside but know that it will not be as good as this one. If you don't mind it being in the tang, get this you will not find anything better. I did all the research for you.
