NextReef NXS1 XL Recirculating Protein Skimmer Information

NextReef NXS1 skimmers feature a fully-sealed, recirculating design, perfect for internal or external use. That means they work as well in your sump as they do sitting next to it. It also means that they`re not picky about water level like many in-sump only models - like an infomercial oven, you can set it and forget it.

Big on performance. Skimmer performance comes down to three things: air, bubble quality and dwell time. NextReef NXS1 skimmers are big on all three, and it`s made possible by the recirculating design. Needlewheel pumps are great for aeraton, but do poorly when also tasked with feeding and maintaining the water level in an in-sump skimmer - the Sicce pump on the NXS1 is used exclusively for air introduction / recirculation, exactly what it does best. Every watt of power goes towards producing air, not wasted lifting water.

NextReef quality goes into every NXS1 skimmer. We have a reputation for overbuilding things, and these are no exception. Each NXS1 skimmer is hand-assembled in the USA, from heavy-gage components, precision machined on our in-house CNC equipment. They`re sturdy, they`re engineered well, and designed to withstand use by demanding hobbiests and commercial facilites alike.

  • Heavy Duty Contruction 1/2" thick flat stock and 1/4" wall acrylic tube. That`s double what most competitors use. They`re heavy, and built for serious use - nothing light or flimsy here...
  • UniSeal fittings on the pump, inlet and outlet. We chose UniSeals because they`re durable - they flex instead of breaking, and provide a stronger interface than acrylic bonded to PVC. They`re watertight, and user-replaceable (Want to modify or reconfigure your NXS1? Go for it!). UniSeals also help isolate vibration and noise from pumps.
  • Sicce PSK Recirculation Pumps. Sicce pumps are quiet, reliable, and low in power consumption. NXS1 skimmers are built around factory-tuned Sicce PSK pumps and NextReef`s custom venturi.
  • Twist-off Cup Assembly. Machined from solid acrylic, all NXS1 skimmers feature an easy to use twist-lock neck. Collection cup maintenece is as easy as a quarter turn.
  • Machined Trasition. Most skimmers use a thermoformed "transition" - the section where the body reduces down to the size of the neck. Because thermoformed transitions are the weakest point on a skimmer, the NextReef NXS1 series features transitions machined from 1" of solid cast acrylic. They look flat from the outside, but inside the transition is milled in a smooth, compound curve to efficiently concentrate the bubbles and waste into the neck.
  • Integrated Silencer. Maximum air with minimum noise. They`re built heavy, too, and they`re easy to remove for cleaning.
  • Recommended Tank Size: Up to 450 gallons (1700L)
  • Height: 27.5" Overall Height (700mm)
  • Footprint: 16" x 16" (410mm x 410mm)
  • Reaction Chamber: 8" x 18" (205mm x 460mm)
  • Power Consumption: 24w
  • Air Intake: 950lph (max)
  • Inlet / Outlet: 1/2" FNPT fitting (replaceable) / 1.25" slip PVC
  • Suggested Water Flow (User supplied pump or gravity fed): 200-400gph (700-1400 l/hr)

Comments: I purchased this skimmer from Marine Depot to be used externally on my 120 reef. It has been running for about a month now and I am pleased with the quantity and quality of skimmate it is producing. This skimmer is replacing an HOB Aqua C Remora Pro that was a great skimmer in its own right, but couldn't quite keep up with the bioload on my 120. I noticed a difference in the water quality within a day or so after setting the NXS1 up. Overall, build quality is excellent, which is required if you are going to use it as an external skimmer. One issue to note is that the 1.25 inch UniSeal for the return was leaking in two places when I received the skimmer. I was able to stop the leak with some Teflon tape and silicon sealant. If you are using this as an in sump skimmer, you would not have to worry about this sort of leak issue, but obviously it is critical when it is operating outside of the sump. Two minor gripes -- my skimmer arrived with no instructions and there was no cap for the drain line from the cup. Both of these are minor items and should not dissuade you from purchasing this skimmer as set up is pretty self-explanatory and it's easy to cap the drain if you chose. The real pluses with this skimmer are: the build quality, the production, and easy maintenance. Break in time was less than 4 hours and no adjustments have been needed since set up. I haven't worked with other skimmers in this price category, but in terms of build quality and skimming effectiveness, I have to believe the NXS1 is up there with the best of the best for the 100 to 200 gallon crowd.
