Anyone used a Nyos skimmer? I am looking at the 300 which gets really great reviews but since it is quite expensive, I am still hoping to hear people's personal experience with the 300 or a smaller version. People claim it is silent and from what I can (or cannot) hear in videos, it is but I am always skeptical when I read that a skimmer is silent.
This will be for a 200G (heavily stocked because of two puffers who never stop eating) and then eventually the plan is a 500G with the same fish.
