so I got a new skimmer last week and it was working ok But it was to deep in the water about 12 inches. I got a stand built and know it sits at about 5.5 inches deep. Manufature recomends 5-8 inches. Could this be causing it to over flow? I have it dialed all the way down both the air and the waterlevel. in the skimmer and its been over flowing for 24 hours st8 now
