The Nyos Quantum 160i skimmer has been presented by Nyos during the 2014 Nuremberg Interzoo.

We tried this protein skimmer in an SPS dominated 600 L tank with a few LPS corals, so it had the though job of keeping the nutrients levels down to a minimum! It seemed a very unlikely chance.
The first thing that comes up to our eyes after removing it from the box is the stunning manufacture level. Nothing has been left to chance, the acrylic quality is incredible, it’s such a shame to hide this protein skimmer in a sump! In my opinion one of the most beautiful I’ve ever seen. I really love that the impeller is in plain sight! But let’s now see all its technical characteristics in details:

Manufacture
As you can see from the pictures, the Nyos Quantum 160 manufacture is incredible, taking protein skimmer construction to the next level. First quality materials along with the perfection of their plastic components combining bring this product to perfection.
The functioning scheme is the usual used by all manufacturer, with some little exceptions like the bonus of having an internal pump. The pump is a Nyos Quantum 3.0 which feeds at 7-8 cm sump level with the water inflow at the bottom.
Water is then pushed to the open view contact chamber with its purple impeller, and from here water and air travel up to the circular diffusion plate. This plate is smaller than the ones we usually see, the holes are also rather smaller than usual. The flow then gets to the skimmer main body through the Nyos “Twister“.
Basically, along the small holes on the plate there are also semicircular holes which are supposed to give water some spinning velocity. This Twister should guarantee a longer contact time.
The skimmer is easily disassembled, showing us the care and modernity applied to this project. From the bottom plate we start mounting the pump in its own box for eliminating vibrations. Take a look at the thickness of the vibration adsorbing material under the pump!
After the pump we assemble the diffusion plate and at last the main body, all to be fixed with titanium screws. The cup is inserted on the body by a mechanism which includes both an o-ring and threading, for an optimal watertight seal. There’s no need of a big effort to remove the cup from the body. We even tried to just lay the cup without screwing it in and in our case it was already enough to make it function perfectly. Just try it!
Here you can see the threading on the skimmer main body.
Above you can see the white o-ring, which will lay on the superior part of the skimmer body even if we don’t screw it in.
We also admire the extreme beauty of the pump visible through the transparent materials, with its Clear View system which allows us to inspect the impeller from the outside so that we can spot any potential problems.
Under the pump plate there are four rubber feet which should adsorb vibrations making this skimmer as silent as possible.
The black silicon rubber feet do their job perfectly.
In the follow video you will see a very nice presentation of the skimmer by Nyos.
