well there a lot available out there. I will be using Euro Reef and turbofloter multi along with CPR/s 294 and refuge w/skimmer. anyways Euro reef is my 1st choice If you talk to the fellas at Premium Aquatics, they are very helpful and can assist you in selecting the correct size. Recently the CS-80 was on sale. not sure now or if that one was right for your system. If you are going to use a wet dry sump, you may also want to check out CPR's 192 and 194 models that include a protein skimmer built in. if you do consider CPR insist on a grounded rio pump with the unit. hope something here helps.
