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

Product Manuals & Documentation

*New Upgrades - Current models include an upgraded bubble plate, 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.

The AquaMaxx HOB Series I protein skimmer relies on a superbly crafted Italian Sicce Syncra 1.0 pump and AquaMaxx needlewheel impeller to vigorously remove waste from your fish or reef tank. Sicce pumps are well-regarded for their efficiency to move air and water. Combining these dynamic pumps with AquaMaxx protein skimmers saves users considerable energy.

  • Dimension : L 7.5 x W 3.5 x H 17 Inch
  • Pump(included): Shark 1.0
  • 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.

Quietest skimmer ever!

Comments: I needed a good hob skimmer for my 29 gallon tank and tho I was hesitant on spending that much for a hob skimmer for my smaller tank. It was worth every penny so far. I took the advice of a couple employees from marine depot and went for it. I have to say it's design and quality are spectacular!!! And is the quietest skimmer I've ever owned glad I went with this over the Red Sea prism that thing is a noise maker a buddy has one. Still waiting to see how this beast is going to perform as far as pulling skimmate but I've been told it's amazing!!!!!! It's breaking in rite now and I barely started adding fish so the best yet to come!

Comments: I have a biocube 29. I tried the tunze 9001 due to all the great forum reviews, save your self the aggravation and go with the aquamaxx. I had to modify my hood but it is well worth it. Simply an amazing product, after one day already producing dark gunk.

Comments: Had this skimmer over my 50 gallon reef tank for over a year and it has performed flawlessly. Performance wise, it started pulling all kind of brownish gunk from my tank from day one. Cleaning wise, the easiest to clean HOB Skimmer. This is hands down the best HOB skimmer I've ever owned and I've owned 5 skimmers. I'm sold on AquaMaxx skimmers.

Great little skimmer

Comments: I have had this skimmer for over a year now and it works great. We just bought a 2nd one for my sister's tank. When I 1st set it up it started skimming within a day, and I get great skim off the tank every day. Its pretty quiet as well. It's also very easy to adjust just move the o-ring up or down to collect more/less skim. I used it in my 28 Gal JBJ Nano cube fits good. I had to cut down the intake tube and to out tube to be able to open up my lid more - that was no biggie. Be careful not to over-tighten the screws or you will bust the hanger (I did that) but super glued it back together and it was fine. Also, there is no real directions on how to put it together you rely on the picture - but it's not super difficult to figure out. I completely remove and scrub everything down about every 6 months to keep it working at top performance.

Comments: After having tried a nano skim, and a cadlights 50 Elite skimmer on my 30 Gallon JBJ rimless reef tank, I can advise that the performance of the aquamaxx HOB - 1 skimmer blows them away, and, there is no comparison. I wish I had bought it first. I am also impressed with the construction, and, ease of cleaning of the skimmer.

Comments: I have a 24g nano reef, the Fluval M60 to be exact. Wanted to upgrade from the Fluval PS1 skimmer that the setup came with. This skimmer is super high quality and sleek. Skimming like a beast after a day. The return can gurgle a little, but you just need to adjust the return pipe. Very happy with my purchase.

Comments: This has to be one of the best if not the best skimmer I've ever used.I've been a reefer since 1995 and have owned many skimmers over the years.the pump is dead silent and the only thing you hear is a little air being drawn in through the silencer.after the first week the micro bubbles will fade away.It's a well made skimmer.

Comments: This skimmer by Aquamaxx does a great job as stated. Pulls out the junk within a day or 2 depending on your water quality. Overall quality is very good, built solid, easy to use. I love the blue acrylic body (nicely done). Highly recommend this product, you won't be disappointed.

Comments: I got this skimmer up and running several days ago and am blown away with the quality and performance so far! It is completely silent and has already begun collecting waste. I have a fully customized Coralife Biocube 29 with a Eshopps 75 sump in the stock stand. The skimmer hangs on the back of the sump which allowed me to convert it to a refugium. I have owned many skimmers in the past and for a hang on the back skimmer, you will not beat this one in quality and performance. Well worth the price!

Comments: I have had this skimmer running for 48hrs now and its starting to break in. when putting it together the pump slips right off the pipe ( seems like this would be a tight fit)I put the cord under the pump when sliding it down to keep it on the pipe, and also the intake piping had to be pushed very hard to stay together.Other than that it is better than the first skimmer i bought for the tank and better than other HOB skimmers i have had. I have this running on an Innovative marine fusion 40 in the second chamber.
