My Lifereef is silent. The air intake goes into the skimmer cup and as long as the lid is on I can't hear it. My tank is in my living room so it being noisy would not work for me. I have not used a Nyos so I can't compare to that. I have used a Alpha 170, RO Recirculated and a BM before and the Life Reef is the quietest out of those that I have had.How noisy are the LifeReef skimmers compared to something like a Nyos ?
