Made in Germany

High performance skimmer for tanks up to 125 gallons (500 liters).

Built to perform
Extreme performance. Very smooth operation. Low power consumption. Easy to maintain.

Extreme performance
Performance, performance and once again performance. NYOS® Quantum® is characterised by high skimming performance as a result of the large amount of air in combination with and optimum air-water mixture.

Very smooth operation
Aquariums should be seen and not heard. That is NYOS® Quantum® is especially silent when running and therefore can hardly be heard.

Low power consumption
NYOS® Quantum® is conceived to be especially energy efficient and uses a minimum of power, despite its huge performance.

Easy to maintain
Consistently strong skimming and simple settings are a joy. For this reason, NYOS® Quantum® is especially easy to maintain and provides the same consistent level of performance over a long period of time. Reliable pump starts are a matter of course.

7 Great Features

1. The new NYOS® Hybrid Wheel
The heart of every skimmer is its propulsion. That is why we have developed a new high-performance drive for the Quantum®: the Hybrid Wheel. This especially precisely manufactured impeller, built with superlight materials, combines the advantages of a needle wheel and a lattice wheel. The Hybrid Wheel is characterised by its lattice-shaped base, on which numerous very narrow needles are mounted. This structure ensures that countless extremely fine micro air bubbles are generated. The greatly reduced weight and the high precision lead to lower maintenance and at the same time low energy consumption.

2. NYOS® Clear-View Reactor
The hybrid wheel needs a pump chamber that is specially adapted to it. That is why we have developed the NYOS® Clear-View Reactor. The Clear-View Reactor is a transparent, performance-optimised large-volume reaction chamber in which the water-air mixture is generated. In combination with the hybrid wheel and the adapted venturi nozzle, it produces an extreme air performance with an optimum air-water ratio. Its transparency means that any foreign bodies can be identified easily. At the same time it is possible to see the huge performance of the pump in operation. Stylish and practical!

3. The NYOS® Twister
Extreme air performance and the finest bubbles are one thing. But in order to achieve optimum skimming, the bubbles that are generated must also remain in contact with the water for as long as possible. That is why, in addition to our normal bubble plate, we have developed the saw-blade shaped Twister. This gives the bubbles an additional spin and swirls them further in a vortex. This greatly increases the contact time of the air bubbles in the water column.

4. Combination of form and function: the Sinus design
Water doesn’t like corners. That is why we have developed a flow-optimised, protected double-S form. In this so-called Sinus design the air bubbles can rise without hindrance and completely free, ergonomically so to speak, without the formation of poor-flow zones at disruptive corners.

5. Precision and details
A good idea must be implemented perfectly to the very last detail. Each Quantum® is therefore characterised by the following: 1. Extremely non-breakable high-performance waves from zirconium dioxide (strength 1600 MPa Vickers hardness) 2. Nine sea-waterproof screws from pure titanium grade 2 3. Precise micro-adjustment screws to fine-tune the water level 4. Full decoupling by means of silicone feet 5. Skimming pot with twist-lock seal 6. Ready-to-use plug-and-play device

6. Optimised, variable setting options
Each aquarium is different. That is why NYOS® Quantum® can be adapted individually to all aquarium conditions: water quantity and air quantity can be set separately and independently of each other. An approximate setting of the water level is achieved by means of the water setting pipe, while the especially precise micro-adjustment screw, which is also included, allows an additional fine-tuning of the water level.

7. Compact construction yet can be dismantled completely
We represent compact, well thought-out solutions. NYOS® Quantum® deliberately does not use any externally mounted, bulky pumps. For us it is self-evident that the device must be able to be dismantled completely.

Pros: Well built product. Very easy to setup.

Clean, well built and easy to setup. I was impressed, I tweaked it twice in two days and it took off skimming like no other skimmer I have ever seen before. Outstanding!

Most finicky protein skimmer I’ve ever dealt with I’m annoyed one minute it’s fine and over night it’s overflowing everything it got out.

Buy this skimmer!

The Best

Pros: Quiet, Efficiency, No break-in period.

Cons: None. It’s worth every penny.

This is the qietest, foamiest, best protien skimmer I have used since starting the hobby 15 years ago. German engineering is still the best.

Best skimmer to date

Pros: Quiet, efficient, and sleek design

Cons: Adjustments can be confusing at first

I had recently purchased this and was skeptical knowing the skimmer drew only 8 watts and was supposedly dead silent. I recently upgraded from an SCA-60 protein skimmer. I was so upset at the fact I did not purchase this sooner! there was virtually no break in and adjustments was easy. Very quiet too. My skimmer right now pulls between dry and wet skimmate and i have to empty my cup every 3 days (heavy bioload. This skimmer is running on my cadlights 42g vera and a 15 gallon bash sea sump.

Best I've ever had

Pros: Easy assembly, quality, skimming beast and dead silent.

Cons: That I had not bought one until now. ;)

I've been in the hobby for ~45 years and have been through more brands of skimmers than I can recall. This is by far more superior than any other brand I've had, and I have had some of the biggest name units.

Great skimmer

Pros: Quite

Cons: Break in was alittle long

I can't say enough about the nyos line of skimmers. There is virtually no noise from the skimmer and build quality is great. Likes to be ran at 8 or 8.5 inches of water. Skimmate is dark and cup is easy to clean.
