Coralife Super Skimmer 125 Set up

Hey all, 
OK, so I've got my Super Skimmer set up and man has it been a bear to get going. I had it running with no microbubbles after several hours of futzing and it was starting to froth, then I was adjusting the pump because there were some micro bubble coming out of there and the hose kept falling off. The thing was a pain to get in in the first place and because it is suspended with nothing to hold it but gravity the thing kept falling off as I moved stuff around. When I got it started up again I was back to where I'd been when I first started it u: a lot of micro bubbles coming out of the diffuser. On top of that, I have the output hose sort of resting on the top of the diffuser sponge because I've read that if it gets water baked up into it, it will not work properly. Downside: The thing is super noisy.
Also, how do you get the collection cup off without taking off the whole collection cup assembly?
here are a couple pics of how I have it set up. Anyone with any experience with these thing have any words of wisdom. I wasn't planning on buying this, but the LFS offered to sell it to me brand new for $95. I couldn't resist that kind of price for a brand new piece.

 

Thanks, Kyle. Yeah, I actually bought a bakpak2 from someone on here, but came across this deal last night and thought, since it was rated for a 125 and that's where I'm going one of these days It might be best to take advantage of the deal and sell the bakpak when I get it. 
I guess the micro bubbles concern me because I had it running since last night with no bubble and now, bubbles and they don't seem to be subsiding the way they did last night.
And...how do you get the cup off? I've been reluctant to force it and the manual doesn't cover it. 

 

Ack. This is making me crazy. I had the thing running and pulling frothy stuff and now the bubbles won't go away. The little nipple at the top of the output broke off at some point. Could that be it?
I've read everything I can on this thing for the past day and have tried just about everything recommended short of modding with PVC. 
I really like this option over the CPR because it has the higher capacity (CPR only rated 60 gallons) and can run in the sump as well as HOB.

 

Thanks Kyle and everyone else. It's settled down some today. Still some bubbles, but not as bad. No skimmate yet, but plenty of bubble in the chamber. I'm keeping my fingers crossed. I will try the cpd when it gets here and keep what works best I suppose. But if I move to a sump the cpd will do me no good. Or will it?

 

OK, the thing's been running since Monday night and other than the hiccups with set up it's been running non-stop. Still no foam. Boo.
