Update: I turned down the two part dosing 72 hours ago from 700 mL/day to 200 mL/day
I just checked my parameters
SG 1.026
pH 8.2
Alk 6.4 Lamotte
Ca 350 (Salifert)
Haven't had a chance to buy a second test kit
By JDieck's calculator I would have to add 769 mL to restore the calcium to 400
My SPS look good. Many are visibly growing
Appreciate the replies

MO Will:
Although there was a drop of 50 ppm in Calcium, there was only a drop of 1.2 dKh in alkalinity over three days. With this drop in Alkalinity the calcium should have dropped only 9 ppm
This show a potential testing error which I would guess is on the calcium side as IME Ca kits have more variability that Alkalinity kits.
(Side Note: I am assuming your LaMotte measures in ppm alkalinity so you are converting to dKh using 17.86 ppm per dKh)
If the alkalinity is right you are only missing about 40 ml/day of recipe. Try using 250 ml/day and watch it over a week's period.
If need to be adjust calcium or alkalinity independently using only the corresponding part.
