Andre,
Yes, that skimmer would work but I would actually recommend the following skimmer if you are looking for that price range:
http://www.coralvue.com/reef-octopus-sro2000int-super-reef-protein-skimmer
It can handle the same load the DCS-170 can but it uses a Bubble Blaster pump which is more reliable and better than the DC pump. Both the SRO 2000 and the DCS-170 are about the same price.
Regards,
