Going back to the OP, there are many ways skimmers create bubbles. Some old, some newer. Needle wheels in my opinion being the most effective happy medium for power usage vs effective. Old technology like the Becket style skimmers push water through a becket which combines air and water and sprays it out with pressure. While very effective it requires a power hungry pump to have enough pressure to function.
