judging by post #9 your box is to high your box water level should be bout 3/4 to 1in lower than tank level .in post 32 i can see your deff sucking air
somewhere .i can see it coming out in sump.if box levels ok try a third utube
worked for me.i have a diy box same size and i found myself closing my input
valve because the utubes couldnt keep up .and my teeth are 1/2 open per.
and a third utube fixed it .someone told me a utube is 500gph a while back
but it is same diameter as 1in but maybe cause the water has to go up and over its true???
