Is there anything I can do to reduce them? I started up my skimmer yesterday, and I am getting tons of them in my tank. My sump only has one compartment with both the return pump and skimmer in it. There are pictures of the set up on my profile. I have been reading that a lot of Microbubbles occur when you first start a skimmer. So will this problem correct with time, or am I going to have to do something about.it?
