Skimmer for "nano predator" tank

[voiceinthedesert]

Hey everyone. I'm starting a 40g cube build and looking for the right skimmer. It's going to be home to a Dwarf Lion and possibly nothing else, fish wise. For corals, I wasn't planning much, maybe some mushrooms, maybe some LPS, but the tank is about the Lion and whatever can live with him.

Been looking into a couple skimmers. The sump I have is smallish, skimmer chamber about 7 inches wide and 11 inches long. As a result, the K2-50/120, Eshopps X-120, Skimz SN-123 and Simplicity 120 have been my main research candidates. I've had the Aquamaxx Co-1 recommended as well, but is definitely the priciest in the list.

I know the Lion is gonna make a mess, but I don't want to oversize the skimmer and have it perform inconsistently. Thoughts on the models I've found? Something else entirely?

I have a 44 gal shallow reef and run a Reef Octopus 110SS which I really like. Skims fantastic and it's very compact.
