Deeper intake does not differ much IMO, Because its already submerged. but surface skimming is the best way to pull proteins.
Tube "A" : i find it better when its just a notch lifted from closed (down) position.
"B" in my case is fully open.
one more thing, make absolutely sure to insert intake "U" tube completely down to the pump intake seat and make it tight.

finally someone! thank you so much!
i think thats my problem its not tight. i opened the A knob a tab and now i m getting air bubbles everywhere. i cleaned my filter pad thing and still air bubbles. any suggestions?
