AquaMaxx HOB-1 Hang-On-Back Protein Skimmer Information

Product Manuals & Documentation

*New Upgrades - Current models include an upgraded bubble plate with conical diffusers, re-designed hang-on bracket, and a larger collection cup as shown in the product photos.

The AquaMaxx Hang on Back Series I (HOB-1) protein skimmer features an incredibly responsive collection cup and an amazingly powerful submersible pump. It is rated up to 75 gallons in a design thin and light enough to be placed on a nano aquarium or other small saltwater aquarium.

The AquaMaxx HOB Series I protein skimmer removes organic waste from aquarium water. It creates a strong mix of small air bubbles and turbulent water movement to force protein, waste and other materials into a collection cup for easy removal.

AquaMaxx skimmers are computer-precision engineered and utilize the latest filtration technology to deliver the performance and value you are looking for in a protein skimmer.

AquaMaxx HOB Series I protein skimmers are easy to setup and maintain. Just move the collection cup up or down to adjust the foam level to wet or dry.

Maintenance is simple. A removable collection cup makes cleaning easy. Plus, every AquaMaxx protein skimmer includes a drain fitting for hobbyists who want to setup a separate reservoir for skimmate.

Water quality and consistency is crucial to the success of a marine aquarium. An AquaMaxx HOB Series I protein skimmer will help to ensure that success.

AquaMaxx protein skimmers were designed from the ground up with the hobbyist in mind. AquaMaxx HOB Series I protein skimmers have the pump placed inside the skimmer itself to save space, reduce noise and improve efficiency.

All AquaMaxx protein skimmers are computer designed. Each unit is precision-cut and made of polished cell-cast acrylic.

AquaMaxx HOB-1 Skimmers feature high-quality Italian-made Sicce pumps. Each Sicce pump motor block is then modified and fitted with proprietary AquaMaxx needle wheel impellers. With the precise modifications and upgrades, performance is boosted much beyond that of a stock pump. The upgraded AquaMaxx ‘Shark’ pump is capable of drawing in significantly more air and chops them up to the optimum bubble size for protein extraction. These pump and protein skimmer combinations deliver unprecedented performance and reliability. Accumulated protein and organics will be vigorously removed from your tank so you can focus less on maintenance and more on enjoying your piece of the reef.

  • Modified and upgraded Italian Sicce needle-wheel pump produces optimum bubble size for high-efficiency protein skimming
  • Efficient, durable and reliable
  • Simple to set up and operate
  • Cell-cast acrylic construction
  • Dimension : L 7.5 x W 3.5 x H 17 Inch
  • Pump: AquaMaxx SHARK 1.0 (modified and upgraded Italian Sicce pump)
  • Pump power consumption: 11 Watts
  • Outlet size: 3/4 Inch
  • Minimum tank height 10-7/8"
  • Filtration Rating: up to 75 Gallons (light bioload) or 40 Gallons (heavy bioload)
  • Requires approximately 4" of clearance to remove collection cup.
  • Fits aquarium rims up to 3/4" thick.
All of our products are backed by a 60-day return policy although the skimmers will also carry a 1-year manufacturer warranty from AquaMaxx. Each skimmer will include detailed instructions and diagrams to help hobbyists get up and running immediately.

*Please Note: Bubble Plate Set Screw (4) has been removed from late models and is no longer included on the skimmer or required for installation.

Comments: I bought this because my local aquarium store highly recommend this for the size and type of aquarium I have. Their price was 229.00. Later they day I searched the interned for a cheaper price and found it here on MarineDepot. Not only are their prices lower than local stores they offer professional tech support. I have called many times for technical support or just advice and each time, everyone is ready and willing to help...this type of support is priceless. Please keep up the great work and I will be back to purchase more. Todd

Comments: The AquaMaxx HOB Hang-On-Back Protein Skimmer is an excellent Product. I started with Sea Clone Skimmer which was a nightmare. The pump inside the tank was a pain to remove and clean. I like that the pump fits inside the unit and not in the tank for easy removal.It's the perfect size for a 55 Gal reef Tank. Highly Recommend this product

Comments: Got this skimmer for my coralife biocube 29. I really like how the intake and the output fit into the first chamber, which allows me to keep the InTank Media Basket and my GFO in the 2nd chamber. The skimmer itself is quiet, has a bit of a gurgle down the output when you shut it off and restart it during feeding. The skimmate is a tea-colored fluid, which is what I'd expect given the rating for this skimmer vs what I have in my tank (4 fish). The breakin-period was about a week, though I didn't have the overflow problem that many people have. The bad about this skimmer is the cup. Namely the band that "holds" the cup in place. Quite frankly it sucks. My skimmer cup will be set, and an hour or 2 later, it's about 2" deeper than it was, and overflowing. Wish Aquamaxx would just make a different design or add a valve so you can adjust the water level in the skimmer. If you're having problems, the workaround that I found was get a rubberband, one of the thick ones. and put use that instead of the orange band Aquamaxx gives you. Been doing this a week, and the skimmer cup hasn't slid down a centimeter as of yet.

Comments: I purchased this for my Nuvo Fusion 20 after finding smaller nano skimmers were extremely hit or miss for customer satisfaction. With a small modification of sawing off a 1/4 inch from the return pipe, it fits great utilizing the second chamber for the intake and return. So far the skimmer is working excellent producing skim every day. It's been about 2 weeks and the microbubbles are getting less prevalent and the skimmer is getting quieter as it breaks in. If you are looking for a great skimmer that you can continue to use as your tanks get bigger, this is a great way to go!

Comments: This Skimmer is doing a great job. Assembly directions could be a little better but once plugged in it started working removing slim. Easy to adjust and cup drain is an added bonus.

Comments: Thanks to will it fit the jbj 28 video and other reviews I got the best skimmer for my tank. The water in my tank was green and it cleared the water to crystal clear over night. I like the way it works and looks. I will buy another one for my other small tank.

Comments: My second skimmer and I expected a lot for the money spent and all the reviews I read. I am not disappointed one bit. It's not too loud in my TV room. It fit behind my tank no problem with 4.25" to the wall. Assembly was a breeze, the instructions were not that great but youtube helped with 1 video. Doesn't heat my water up. Pulled wet skim for a couple days and within 1 week I had the nasty dark green funk you expect. The smell of the collection cup was hog heaven for a better term. I recommend this to anyone that has a I am nervous about skimmers attitude. Hassle free and only adjustment is cup up or down.

Comments: As others have noted the instructions are lacking, but otherwise it's a great skimmer. Easy to disassemble and clean, easy to reassemble once you figure out the directions, motor is damn expensive to replace but should last according to reviews, quiet if you set it up properly.

Comments: I have this for my 36 gall tank. I was a bit hesitant to spend this much but took the recommendation of the marine depot staff. I ad a rough time getting it going. When I first started it, the collection cup would fill up in 30 seconds. When i called marine depot they suggested taking the lid or the whole collection cup out but couldnt do that or it would have spilled all over the floor. The second call they suggested putting in my back up water container to let the organics build up in it. I did that for a week and was then able to let it run for about 2 minutes before it overflowed. I had given up on it and was about to buy another one when by accident I plugged it back in and now it works fine. Its very quiet and is pulling gunk out of my tank. Its only been running a week now, but seems to be doing well.
