Micro-bubbles

Hi all,
I'm a newbie, my tank has been up 4 months AC(after cycle) I have a AquaC remora pro HOB skimmer, I chose not to use the pre-filter/bubble reducer box since it is sized for a mag3 pump and is [huge] in a 45g. I hate the bubbles and understand they may simmer down once the skimmer has "seasoned". Is there anything I can do to reduce this, I tried putting a sponge in the opening of the return waterfall but that didn't work out too well.
