120 - 200 litres per hour is recommended by the manufacturers. So if you can get a pump that does between 500 and 1000 lph, that should be fine considering head loss etc.

You don't need huge flow, basically the smallest pump that will fit your reactor.

Pete - I hope you don't mind - I just changed the title of the thread to something more understandable.

I would say go for a power-head of at least 400 litres per hour, because taking into account that the media might compact at some stage, and that you need the extra "water push" to ensure that the water actually comes out of the reactor. I run a 500 litre per hour on my phosphate reactor, and after the 2nd or 3rd day after replacing the media, the water trickles out (it only runs "strong'ish" for the 1st 3 days or so).....

Put the purigen in a canister filter, it needs as much contact with water as possible. Hang it in your sump.

A phosphate reactor is much more efficient than a filer sock in a cannister, get a proper reactor if you can.
