What Nyos Quantum 160 owners say

It was overkill for a bit, but, now that my tang and filefish are bigger, it feels just right.

I love my NYOS 160 which I have had for over a year now. When the pump needs cleaning I do have to lift the unit out of the water to get it primed and started.

My Nyos 160 does the same thing regardless of how recently it was cleaned. I have to lift it out of the water as well. Nice skimmer but for the money I feel there are much better products out there
