there is some truth in your concern, flow will straighten out the further you get from a tee or elbow. It wont be a big deal but if you can move it maybe 5 pipe diameters downstream of the last tee it should help some. Also don't submerge your recirc line in your sump, you don't want to push the air below the water level in the sump. If you are concerned with splashing, just add a tee to the end of the line to break the flow. Install the tee so the there is a horizontal run that is at sump level where air can escape but ownt splash.
Got it, makes total sense. I didn't figure bubbles would be inclined to travel upstream as it were. I'll definitely modify the output so it's not submerged as well.
