Powerjet Nozzle on the Rena XP

There's a venturi that comes with it?
 
Because of this post, I put the power jet on last night. The fish hated it... they hid in the opposite corner.

However, I moved some decorations around to give some more cover and what not and they seemed ok...swimming near the new structures. If they don't like the new stream of water after a day or two, I'm switching back (until I make my own return :) )
 
Its a part of the flow control nob, that piece that sticks up out of the top of the knob is the cap over the venturi(pull it off). I've not bothered to ever hook up that flow control peice personally.

Right on! That's great! I didn't know that.
