Jonathon ... Here is a surge system that looks very interesting ( no bubbles too
) ... I plan to try it out some time this summer as I am desperate for more flow ( have about 4600G/Hr now and it is not enough )

another option I am considering is the penductors but I will have to change my ( 2 x ) Mag18's to ( 2 x ) Mak4 or 5's ( or eqivalent ) in order for them to be effective.
Tony does make alot of sense in using the pressure rated pump where you have the most elbows.
Cheers
