hi guys,
today i got nothing to do so i thought of adding an air pump to the air inlet of the venturi.
previously, i can see the central tube in the chamber but now, after blasting it with a beetle 600 air pump, got so many bubble, cannot see the tube liao.
big bubbles, small bubbles, swirling left, swirling right, now skimmate twice as much and twice as
