I checked my PH about 6 hours after the 2nd dose (which i did 12 hrs after the first dose) and it was stable at 8.4 and none of my corals, my shrimp or Mandarin look stressed. After the first dose my calcium was at 380.

My Mg is at 1150 and my dKH is 11.

You already put a mandarin in your tank ? I thought you were going to hold off on that until your tank was more established ?
