I've had this skimmer for about 6 months now and apparently am still failing to tune it properly. I watched several videos online that say to tune it so that the bubbles break at the neck. However I always end up with a giant bubble bath in my sump just days later. I have continued to tune it lower and lower (currently the bubbles break only a couple inches above the inlet) but still the same results. I attached 2 pics one of where the big bubbles currently break and two is the aftermath. Any thoughts?
