“It was overkill for a bit, but, now that my tang and filefish are bigger, it feels just right.”
“I have the Nyos 160 & it's very quite, the issue I've had is set it & forget it. it seems to run great for a month or 2 & then all the sudden wants to start pushing water like mad”
“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”
“And boy, was I happy! I am very sensitive to noise, and this one performed, and was silent! But now, over the past few weeks, the skimmer is starting to make a lot of noise!”
“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.”
“I bought a Nyos 160 because it was meant to be soooo quiet, it's not that quiet, 3 months in and I find this issue of not starting after feeds,”
“Mine did that and for the price I paid for that skimmer I was highly disappointed. Other than that being the only issues the skimmer performs well and quiet.”
“I purchased a Nyos Quantine 160 skimmer from Aquacave on 1/25/2016 and I have been having trouble with it. Aquacave has been very helpful, however the skimmer is not working correctly after approximately 3 weeks of operation.”
“I've been using the NYOS Quantum 160 for almost a year and it has been a great experience. I only wish the cup was easier to remove. But it works great.”
“I ran a NYOS160 for about 5 years. It's a phenomenal skimmer. Expensive but easy to dial in and it pulls a lot of air for low wattage. Quiet too.”
“With skimmer not running: Avg 28.6 dB With skimmer running: Avg 33.7 dB I have the Nyos Quantum 160. Skimmer is in the sump, cabinet doors closed.”
“I have the Nyos 160, and I agree with The Camaro Show, go with the Reef Octo. IMO the Nyos is not worth the price tag”
“I love Nyos tanks, but for me the sump is a bit too small and the layout is awkward.”
“I would purchase a Nyos again with out a thought. They were/are easy to adjust, very quiet, easy to dismantle to clean.”
“Read many of the posts on here saying the NYOS 160 is as quiet as they come, saw a bunch of videos on youtube stating the same thing, the sight advertises “silent” and I’m feeling like I’ve been had. Hooked it up and no change compared to my redsea 300 (ac).”
“I ran it as an air pump for 2 years because I could never get it right. It was always overflowing or not producing bubbles. Since I have it figured out last couple years it is great. I am 100% Nyos fan now, just very annoying at the begging.”
“I do have problems getting it to start up if I haven’t cleaned it for quite awhile.”
“It suddenly started making a really loud humming noise which I can only stop when I close the air intake valve almost completly. Problem: With the Air Intake Valve closed almost completly, I'm getting a sh*t ton of micro bubbles. I've completly cleaned the skimmer several times, the noise stays.”
“Very annoying that you have to do this to a $500 skimmer!”
“I've had my NYOS Quantum 160 running for around 6-8 weeks in my Red Sea Max S 650 and it's the best change I've made. Exactly as you said above the stuff it pulls out is amazing and straight out of the box. I'd never seen such black nasty stuff before!”
“I've had this skimmer for nearly a year now (bought used). Worked fine for about 4 months, then the problems began - micro bubbles and the main issue being the skimmer cup getting flooded. Working fine one minute, later that day totally flooded and just running back into sump. I've tried everything. This skimmer is about to go in the bin.”
“Been running the nyos 160 for a year now on my reefer 350, great skimmer, very quiet, easy to dial in.”
“I loved my Nyos, it did an amazing job, but this issue is a deal breaker for me, especially with the money that I spent. I've read where others bought a replacement pump (I believe it's stronger) that resolved the problem. The other big issue is with this skimmer is the amount of parts that need to be cleaned unassembled and reassembled each time you clean it.”
“I have 160 for a year and half. After a long period of no cleaning the skimmer I had it not primed itself everytime it restarts. Figured out to blow into venturi line as well. But after deep cleaning for 2 months I didn't have the self prime failed on me again. Other than that it is a pretty solid skimmer.”
