It just seems that with lower nutrient levels corals cannot "adapt (or tolerate)" to the higher alkalinity levels..

Now you didn't mention any specific nutrient levels of neither nitrates nor phosphates but I'd bet that the vodka is causing your nutrient levels to be lower (as it should) thus the corals cannot tolerate the higher alk without getting burnt..

I'm sure there is likely a scientific answer where one plots zooxanthellae growth rates against coral calcification rates and shows an imbalance that forms in your situation and thus the zoox cannot keep up with calcification or whatever..
