Alk is at 8. I finally resorted to the baking soda to get the PH to stop dropping. Stabalized now at 7.8, I am afraid to run more. I do have the skimmer airline coming in from outside. I also ran a bubbler and wedged the airhose in the grates of a powerhead, that really kicks out some air bubbles. Not ideal, but better than losing all my livestock.

Before I turn that reactor on again I am taking out 3/4 of the media!
