New ER Skimmer starting to tick me off:(

[findingnemo1]

Hi there.

We have a new rs250 and have had it running for about 4 days now i guess. But yet all i am getting is light green water and even that is not alot. I know it needs time to break in but my god i got more out of my remora when i bought it. And i know the tank has junk in it so its not that. I read all these posts and see all these pics about the dark black gunk coming out in 48 hours but for me it just isn't working.
Oh yah and this is on a 90 and i know it is overkill but hey it was a good deal and i would rather overskim than underskim
So i guess the big question is how do i dial this thing in?
Any suggestions on how everyone got theres running good?

Thanks
Craig
