You know... I started this 180g custom corner tank running an ASM G3 skimmer with the Cedric5000 pump. After about 8 months of high nutrients, I upgraded the sump to 50g and I added a Reef Octopus skimmer and so I was dealing with emptying 2 skimmer cups every couple of days. And of course, the noise! Yikes, the Db increase on the TV just to compete with the noise! The ability to fine tune in so many ways, this new AerAqua Skimmer is a big plus. It's nearly dead quiet, a huge plus. I know it's only been a few days, but... I would highly recommend this skimmer! Oh, and because I already have two Gyres with the ICV6 controller, I added the skimmer to the iOS app on my iPhone. It was a seamless addition, no hiccups. Very cool. The one question I have, according to what I've read, is about the "sweet spot" buttons on the side of the body. The water level in my sump is about 4" above the sweet spot buttons, however the water level on the inside of body is right at the sweet spot buttons. Do I raise the skimmer so that the water level on the outside of the skimmer is at the buttons? Or does the sweet spot mean for the water level inside the skimmer? I'm following the instructions that say to leave the adjustments until after a one week break in period. So far, so great!
