i just got my potein skimmer today. i set it up and its running now. The directions say to adjust the air flow to reduce the tiny white bubbles. -
-do i want to have no little bubbles, or do i want lots?
Bubbles are what allows a protien skimmer do its job. That said too many bubbles is a not necessarily a good thing either as your not getting enough water in circulation. Thats why we all have a tendency to "tweak" our skimmers. I generally adjust my skimmer so I get a steady flow of bubbles in the bottom 1/4 of my entry tube. HOWEVER not all skimmers are created equal and you'll have to see what works best for you.
