So, I finally measured my alkalinity today after almost 2 weeks since the last measurement. It measured 6.4 and I normally keep it (or at least try to keep it) at 8.0. Amazingly, everything looks pretty good although colors are off on A. vermiculata (canary in a coal mine?) and a wild pink chalice I picked up some time ago. I always thought the Strawberry Shortcake was sensitive but is looks fine. Anyone else care to post their observations regarding alkalinity changes? Guess I need to re-evaluate my daily alkalinity demands...
