Fish toys, gotta love 'em :-)
Here we have the fancy schmancy Vertex UF-15 Media Reactor.  Great for tumbling oh.. say.. some NP bio pellets perhaps? 
The inlet and outlets are 3/4" so I needed to get a couple of adapters in order to hook the inlet up to a maxijet 1200 and to get the outlet to bend back into the sump.  It is a fairly sizable reactor that can go in or out of the sump.
Bye bye phosban reactor, hello new hotness.
One mod I did perform was to cut the stock sponges in half.  They were really really thick!  I shaved them down to about a half a centimeter in thickness.  If I had enkamat I probably would have used that, but sadly I do not have any enkamat 
And here they are tumbling the day away..
