Well we mine limestone by the shit ton. Lime water gives you CaOH. What would it take to adjust? I'm not a chemist so I have no idea. It also just happens that my underground limestone mine also has a layer about 100' above the limestone layer filled with salt water. It rains from the ceiling.

Lime (CaO+H2O—>Ca(OH)2) is derived from limestone (CaCO3). So, you need to release CO2 to make lime, which can then capture CO2 again. No net gain of CO2 fixation.
