I have recently switched over to BBB from pucks, and now I'm experiencing a gradual rise in PH.
How much aeration does it take to cause the PH to rise? I set 2 of my returns to just barely break the surface in an attempt to increase surface circulation to the skimmer. You can see that the return water is breaking the surface, but not enough to cause any bubbles. Is this enough to cause a rise in PH or is it something else I'm doing?
