Daily changes in Ca and Alk

I have been dialing in my tank and in the last 30 days I have been getting some remarkable growth. Coral that wasn't doing much for months now is nice and puffy with gorgeous extensions. The colors are so vibrant I hardly believe its my tank.

Anyway, up till 2 weeks ago I checked alk, ph, ca...etc every saturday and it was always the same values that needed a small bump for dosing. I do use 2 TBS of kalk per gallon in my ATO. Before this the fluctuations in ph alk and ca were large

I do not know if its because my stony corals are growing a lot, but now I have to dose buffer and Ca almost everyday to keep levels stable. This is on top of the Kalk. When I test i'm an Alk of 8.5 , pH 8.0, Ca 420. I raise it to Alk 12, Ca 440 and pH 8.3

I have a small 40 gallon tank with 25 gallons of water. Is this a normal swing?
