Assuming we don't get a stellar deal on another decent brand used when setting up a 40b reef, I will be making my future bro-in-law buy an octopus. Rock solid standalone skimmer. If you want an all in one skimmer sump I really love my CPR CY series. In his case we are making a 29g sump/fuge so he has a huge variety of choice for skimmer like you.
