29g Nano Skimmer Help

Somewhat new to the reef world, I am in the process of setting up a 30g nano tank. It is hard plumbed with a sump/refugium. I am setting it up with a calcium reactor that I got for a solid deal, and am in need of a skimmer as well, as I dont want to worry to much about my bioload. I am looking for something under 200$ and my sump space for the skimmer/pump is 13" x 7", with about 25 inches of room vertically within my cabinet. Help form some more experienced reef tankers with choosing a brand/model number that is at least +1 would be very helpful!



Thanks
