I didn't know you could adjust the bubble size in a skimmer. I thought that was set by the pin wheel, so by restricting air flow would only change the number of bubbles.

It looks like Whatcanyoudo has a downdraft or Beckett style skimmer which does offer some control over bubble size. The needle or pin wheel style skimmers chop the air into bubbles without any control over the size. The Euroreef that Milan has is a needle wheel style so there is no way of choosing the bubble size, only the volume of air supplied. Ultimately the goal is to have the bubble chopped as fine as possible with as much air draw as the pump needle wheel can "chew up". I think Milan was referring to "bubble height" and not size.
