I just added a Nero 3 to my 65g reef. I also have a Nero 5 that I’ve had for a long time. The Nero 3 is really noisy compared to the 5. There’s nothing in it, and if I take it off the magnet, it’s quiet. So apparently some kind of vibration when on the magnet mount. I tried taking the nem guard off but that didn’t fix it. Any ideas?
