Milad - have you watched the You-Tube videos done by LA Fish Guy when he goes to Reef Dynamics and talks to the owner? They're pretty good.
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. I'm no expert by any stretch of the imagination - my Reef Dynamics is still breaking in.
