First question is the protein skimmer. Shouldn't more foam be climbing the neck? If I close the red valve, water travels up it, not so much foam. Should I leave it or adjust the valve?
Also I have water coming down my secondary drain pipe from my shadow. Should I make the tube a tad higher in the overflow? I have the gate valve on main drain all the way open
