What pump for phosban reactor?
 

I am running mine off of a maxi jet 600, I have to use the ball valve to throttle it back. The pump does not seem to like this because it chatters loudly.
Which pump should I use?
Which do you use and how does it work?

minijet 606. You will throttle it back a bit too, but that's the one MarineDepot Recommends. Works well for me.
