When the nozzle is set properly, the line where bubbles turn to foam will be around 2" or a bit more below the white collar where the cup attaches to the body with the wedge pipe fully open. From there, you use the wedge pipe to adjust from wet to dry. Keep in mind that it will take several days for the skimmer to fully break in so you will likely need to do your final tuning after a week or so. Also, it's best to use gloves when making the nozzle adjustments so the oils from your skin to impact the skimmer forcing you to wait hours before the skimmer settles back down in order to see the results from your adjustments.

Thanks for the quick responses. I moved the skimmer up to 6.75" and backed the Venturi out 5.5 turns with the air tube set to the first line.
I have no fish in the system yet, just CUC and dirty Pukani rock. Skimmer has been overflowing still so have the drain plug pulled, gonna just let it settle down.
