IOAOI Protein Skimmers for Saltwater Aquariums, Hang On Protein Skimmer for Fish Tanks up to 80 Gallons, DC Pinwheel Pump with Controller, Not for Rimmed Tank

This skimmer is a beast! I’m using it in an IM Nuvo Fusion Pro 40 gallon. It fits perfectly in the chamber between the return and the overflow, albeit minus the hanging bracket which is not needed because the chamber is the perfect depth. This is an upgrade from the Fiji Cube Nano Skimmer which constantly overflowed when water levels changed, even when I activated feed mode. The IOAIO sits much higher with the top of the vortex chamber well above the normal water level. I love that it has both an air intake adjustment as well as vortex chamber water level adjustment. This made fine tuning it a breeze. In addition is has a wave mode, constant mode, and feed mode plus 10 levels of speed. I’m running it on speed 5 constant with the vortex chamber just slightly open and air intake fully open. I get an amazing bubble column and I can watch the denser bubbles push towards the top until they overflow into the cup. Within a few hours of installing I had a nice brown sludge in the collection cup. I haven’t had to mess with the setting much at all. It’s extremely quiet compared to my old skimmer. The collection cup is so big I’m not even sure I need to use the drain valve but I love that it has one as my old skimmer did not and constantly overflowed. Putting it together was incredibly simple. It seems very sturdy and holds together well. Removing the collection cup to empty it is very easy. This is a 10 out of 10 skimmer. I wish they made a smaller version for nano tanks.

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.

IM50 Lagoon. Very Quiet! Fits perfect on left side compartment 2 , where original IM medium skimmer fits. Two days in nice dark skimming. The pump is the most impressive 3 times the size of OEM IM. I feel this is doing such a better job! The only issue is the air line has to be disconnected to clean and empty the collection up well. Only reason for the four stars. Otherwise I would buy all day long. Great skimmer.

I have been running this skimmer a week now, and I'm beyond impressed. It has adjustments for the height in water, adjustment for speed of the motor, adjustment for air flow, and adjustment for water release. That said, that does mean it can be a little tricky to get dialed in, but when you do, oh boy. This thing makes great bubbles, great foam, and pulls out all the nasties. After the break in period I'm running the pump at 5/10 and have the water level about 1" above the outlet tube. This has been getting me a decent wetish skim. I can't say enough good things about this skimmer, for the cost, it cannot be beat and it's absolutely silent. I'm running it on a waterbox 50 AIO in the second chamber. I did have a ton of micro bubbles in the display for the first 2 or 3 days, but as the skimmer breaks in these are reduced to almost none. I plan on adding a mesh bubble trap before my return to capture the few remaining strays, but even as is, I'm perfectly happy.

I have gone thru two of these units. First one was purchase new and received used. It wasn’t evern cleaned and covered in salt creep still. Second unit I got set up and was working great for two days. Then the controller for no reason, just stopped working. Pump was working fine and outlet was fine, controller just turned off and never turned back on again.

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!

Worked great for about a year and then started reading an error code. I tried taking it apart and cleaning it well, which would fix it for a few days and then it would start flashing the error code again. I assume the motor is probably going out. A little disappointed it didn’t hold up long

I can’t speak to longevity yet, but the performance for the size of this skimmer is awesome. It replaced a Sicce Shark 300 that worked okay, but this IOAOI is easily 10× the unit. Attached is a photo of its very first run with about 30 hours of collection — it smelled disgusting. The Sicce wishes it could produce that kind of nastiness. I’d recommend it if you have a small tank and limited space. This one is in the back of my Sea Cardinal 50 AIO, which has pretty narrow chambers. It fit without the bracket and is sitting in 7½” of water. Running air wide open, chamber wide open, and the pump at 5.

Al principio te cuesta saber si esta funcionando pero después le agarras la onda y sirve excelente

Skimmer came well packaged in closed cell foam. Individually wrapped pieces. As with all equipment a good rinse and wipe down should be conducted before use. There was some sticky residue from the plastic wrap present on the plastic. With normal skimmer installations I usually 'break it in' with some dirty tank water and vinegar. It helps build up a bacteria film in the skimmer which helps with bubble production. Do this for at least 12-24 hours prior to skimmer installation. To fit in the filter compartment of the Innovative Marine AIO 50, I had to remove the 2 levelling screws on the back of the unit which wouldn't be used anyways since it's a snug fit and the hang on bracket isn't used. For the first day or two, set the skimmer on low, and let it break in further before really trying to dial in the skimmer. Within a day, it was producing a decent wet skimmate. The air intake adjustment didn't seem to do much, but for a simple drop in solution, the pump intensity is all the dialing one should need with such a skimmer. Quite impressed with this IOAOI Skimmer!

Producto de muy buena calidad, por el momento todo bien, fácil de ajustar…

This skimmer is fantastic. During setup I think I exclaimed “oh wow!” and “oh that’s cool!” a dozen times. I’m used to old-school cheapie skimmers in previous reef keeping experiences and I can tell you this one is way beyond that in functionality, ease of use, quality of materials, and omg it’s SO QUIET!!! I’m very pleased. I was skeptical and going to purchase the popular expensive brand out right now but decided to take the chance here and invest more into other start up areas. So glad we did!

Después de un año ah quedado inservible, el controlador ya no encendió y no hay refacciones por ningún lado, por un poco más de dinero recomiendo comprar una marca diferente que cuente con servicio post venta
