Is there a more efficient/proper way to set up spray bars?
1) I've noticed that If I set the spray bar a little higher than my water line, the output splashes with more force which creates thousands of mini air bubbles that flow through the tank.
2) If I set the bar up on the water line, the water just comes through with little splash and doesn't create as many bubbles.
Is option 1 more beneficial for the fish/water quality because of the bubbles. Bubbles do bring gases to the surface I've been told or read somewhere.
