Functioning
The skimmer is ready to work as soon as we place it in sump, the foam fills the body cone up to its neck and in the cup. The foam is soft and soapy, made up of tiny bubbles. When the cup is on, the bubbles go up in its neck and become bigger, just like in any other skimmer. The foam seem of very good quality by observations.
We suggest to keep your sump level around 20 cm, at this level water pressure and air inflow are perfectly balanced. They are because this skimmer is build this way, not for any other reason. We kept our sump level at around 23 cm without noticing any problems, with excellent results.
The skimmer has been used in a very loaded tank with nutrients level close to zero. The aquarium was an Elos 150 custom 150x60x50h lighted by three Ceab Slide & Led (italian review) and later by two 250 watt HQi. Water flow is managed by a pair of Vortech MP40w (english review).
To give you an idea of how the Nyos Quantum 160 skimmer works, we show you this picture of the foam after 3 days of functioning.
Below you can find a picture in more details: you can see the soft bubbles in the cup together with the bigger bubbles, like we explained before.
To end up this load of pictures I want to show you the material that sticks on the cup lid.
You can see the soapy texture of the foam, it has the right colour and texture. We can consider this a dry foam but with a muddy leftover on the cup lid. The foam runs easily up the cup neck even immediately after cleaning it, with its very small bubbles.
After the 6 months trial during which we continuously used the skimmer we can consider ourselves very pleased with the Nyos Quantum 160 skimmer. If we run a very dry foam we will have a thick leftover which will cover the cup neck in around three days, after which the foam will no longer be able to climb into the cup and the skimmer performance will be lowered until we clean it.
