Depending on how your sump is set up....Remora and Remora Pro can both be used as a HOB and in sump. AquaC does have an in sump model, but the Remora will work in a sump as well.

Thing is that I dont have a sump on my 55 I am upgrading in a few months to 125 gal with a sump. I need a better skimmer on my 55 until then. Right now I am using a seaclone and its not keeping up.
