I'm studying the pictures to see how on earth you got the areation going. Yes, I love that and I tried different ways to make mine do that. My husband even drilled a hole in the outlet nozzle thinking it would suck air through there and create bubbles. I love how the bubbles look but hate airstones. Yes, the flow does look a heck of a lot stronger than your 1st pic lol
... where the hose and the nozzle meet, I put the OD of the air line with the nozzle and put both into the hose... no flow is interupted because the flow is going down thru the hose... I just put the airline in the back of the connecting pcs
