protein skimming help

[REDNECK_REEFER]

hey guys and girls I just picked up a schuran protein skimmer. Just wondering if these things are any good. It looks high quality. but it has no pump for it. I'm currently running a 90 gal with a 55 gal sump. will this skimmer do the trick?

This skimmer is 2ft tall 4-5'' around and has a 3/4'' input I think they use eheim pumps but i don't know which one to get.

Thanks for the help!!!

P.S. i'm running a mini g skimmer right now with a sedra 350gph pump.
