Honestly it's been pretty straight forward. I had to play with my AquaC for weeks before I could get it to run correctly, and then it would be all wrong the next day. Right now I'm just adjusting plus or minus with the ball valve to get the foam head to fall over the edge of the cup. I wanted to play with this for a few days, then turn off the pumps, set the water to the bottom of the union, and fire it up to see how it does.
I have a pretty light bioload (2 small clown, 2 small goby) so I'm not getting a ton of junk, but it's very apparent it's a lot more than my AquaC was. I got this not only because I could easily place it outside of the sump, but more importantly I see a 150-300 gallon in my future. This is 10x the skimmer I need for this tank, but I will be able to run both tanks off of the same sump and not have to buy another skimmer.
