Any recirculating skimmer can be gravity fed. These skimmers are way more than 20 bucks though, so that might not be what you're asking about.
No no no. This is stupid simple. Take your return and it goes into like a 10" X 10" closed box with about a 4 inch cylinder coming out of the top about 8 inches. The cylinder has a 1 inch tube out of the top of it and the bubbles and skimmate goes out the tube into a collection apparatus. So, return water hits the box, creates bubbles and out they go?
