Yes, the higher the alkalinity the more stable pH will be because it provides higher buffering against pH rises and falls.

alk is at 9 right now. corals seem to like it better. calcium is staying at around 420 so there is no need to dose extra yet. id like to try 10-11dkh and see how the corals react.

pH, carbonate alkalinity and CO2 are mathematically related and knowing two gives you the third.
Limewater (kalkwasser) raises pH because it consumes CO2 in the tank to form bicarbonate and carbonate from the hydroxide it adds and the CO2 in the water: OH- + CO2 --> HCO3-

got it....
is it possible to hurt corals by having a lack of co2? i would think it wouldnt harm fish. |

There is no lack of CO2 unless the pH is too high, and that brings its own problems.
