Non sump/nonhang on the back skimmers

Are there skimmers that can set below a tank that don't work off
the sump. Otherwords like those stand-a-alone media filters that suck it in and spit it back up into the tank.
I have a 120 gal tank with hand on the back skimmers, was thinking about a overflow but would prefer the above. Certainly at public aquariums but can the hobbist?
