Well its a venturi system all right, air getting sucked in & through the properler housing. Uve already fired it up> Is it noisey enough to keep you awake?
lol
These units create a vortex within the chamber that does take some time to get in a rythum, looking at it logicly the smaller the bubbles with the least amount of turbulance will produce the most effecient mean to skim. But breaking in down abit more technical could help (ha-go figure) if u think of a water molecule as a magnetic ball-bearing it might help mentally
As the bubble travels up through the water column, the elecrically charged protein molecules (which contain elecrically polar and electrically nonpolar regions) are attracted to the air/water interface of the bubble. The polar regions of the molecule (made up of nitrogens, oxygens, etc) are attracted to the air/water interface and these polar "tails" stick out away from the air bubble into the water column. The nonpolar regions stick out into the air bubble because it does not "like" to be in contact with the polar solvent (i.e. water).

If you could look at this bubble under high enough magnification down to the molecular level, the entire air bubble would look like a fuzzy ball with protein tails and other electrically charged tails sticking out from the surface of the air bubble. The polar regions outside of the air bubble stabilize the air bubble very much like a soap bubble in your kitchen sink or your washing machine. This is why a foam begins to build up at the surface of the
skimmer. As the protein laden bubble reaches the top of the protein
skimmer, the proteins begin to accumulate which creates a stable foam bubble. These stable foam bubbles take a long time to pop. Thus, the proteins slowly are concentrated at the top of the
skimmer where they are slowly pushed through the "throat" of the protein
skimmer and into the collection cup.

The next most important factor to keep in mind is minimizing turbulence of the air bubbles inside the
skimmer! The reason for this is because of the
different types of dissolved organics in the water column. Different organics are attracted to the surface of the air bubbles to a different degree depending upon the molecular composition of the dissolved compound. Some compounds are highly attracted to the air bubble. Others are only weakly attracted. If the air/water is turbulent inside the
skimmer, the strongly attracted compounds will stay attached to the air bubble but the weakly attracted compounds will not and they will not be skimmed out of the water column. By minimizing the turbulence inside the
skimmer, both the strongly and weakly attracted compounds stay attached to the air bubble and are skimmed out of the water column. What you want to see is a nice blooming flow of air bubbles upward in the water column. If you see excessive turbulence inside of the
skimmer then the
skimmer is not tuned properly.
