Going to start dosing alk my ca stay steady at 420 because of my daily automatic water changes I presume. But my alk drop .3 dkh per day on 190 total gal water. (Tank + sump- rock sand).

I will be using esv liquid carbonate which will raise alk 2.06 dkh per 1ml per gal of water.

I figure I need approx 1/8th of ml per gal to maintain alk. 2.06/8= .275

Therefore .08 ml per gal will raise alk .275
So .08X190= 15.2 ml per day

Does this seem correct?

You would need .15 ml per gallon. .3 dkh is 15% of 2 dkh.

.15 x 190 is 28.5 ml, by my math. You're not far off at 1/8 ml per gallon but that's .125, not .08.
