Thank you for contacting us. Unfortunately, the Prime skimmers may not be the best fit for your tank. The Prime 150 might be a tight fit on your bioload and the Prime 200 is too big of a skimmer for your system.
I would actually recommend any of the following skimmers instead:
Classic 150INT... http://www.coralvue.com/classic-150-int-protein-skimmer
Classic 160INT... http://www.coralvue.com/classic-160-protein-skimmer
SRO 2000INT... http://www.coralvue.com/reef-octopus-sro2000int-super-reef-protein-skimmer
