See my posts above. Screw it in clockwise until it's tight. Mark it with a sharpie pen with a straight line across the top of the nozzle and the part it threads into so you have a reference point. Unscrew the nozzle 4 1/2 full turns out from fully closed and start there. The manual states a starting point of 1.5 turns out and in my experience, that is not a good setting for this skimmer. The ideal setting is anywhere from 4 to 5 full turns out from fully closed and a sump depth of 6.5" - 7.5" depending on the load. I would normally suggest a starting depth of 6.75" with the wedge pipe wide open.

You want the water/fast moving bubbles to transition to foam right around to top side of the white flange where the neck threads to the skimmer body. You should see a solid obvious line in the neck where this transition from bubbles to foam occurs. If the load is light or if you want a wetter skim, you will raise that line up higher in the neck. If the skimmate is too wet or if you are having issues with it overflowing then you may need that transition line to be lower. It's heavily dependent on the load. In a heavy load, the skimmer will generate more foam and that necessates a lower level in the skimmer. Once the skimmer catches up and reduces the amount of dissolved organics, you will likely need to make an adjustment in the level inside the skimmer to fine tune it so it remains consistent.
