It has been 96 hours since I achieved 420 calcium, and seized dosing pump. Calcium went from 420 to 400 dropped 20 ppm in 3 days. Alk started 9.6 went to 8.5. Should I calculate and turn pump on now or continue to test for another 3 days to see if it drops consistant?

I'd go ahead and calculate. Three days is a good duration to collect data on usage.

Yes sounds like your ready to do the math... determine the amount to get it back to normal... dose that... then divide that amount by 3 and then dose that amount each day after. Keep testing after that to make sure things are level and adjust.
