hey Tony,
       Not hooked up yet.  I was hoping for the PVC today but I'm sure the long week end added a couple of days to the shipping.
It's my own anal retentiveness that is causeing the delay.  There are many easy solutions using imperial measurement PVC, but I like the idea of correctly fitting pieces.
I heard from Royal Executive that the next version of BK headed to North America will be all imperial fittings.
I have built a self unit above my sump and will put the skimmer on it.  I'm using a MAG 5 for a feed pump.  It's an odd design as the MAG feeds directly into the Dragon pump.  I guess the feed pump is really only to ensure water gets to the skimmer.  In hind sight I could have just gone with an internal BK.  But this will look cooler 

Water level isn't really a factor with the external it just has a 600GPH max feed restriction.
That reminds me I'm going to call the PVC people
