Dosing 2 Part

Hello All. I'm cycling my 180 DT currently to eventually be SPS dominant. I have dosing equipment for 2 part via (2) BRS 1.1ml/min doing pumps controlled by Neptune Apex. My main goal is to achieve stability for SPS using 2 part.

What are your thoughts on these 2 options:

1. Dose Alk during off light cycle for 10 hours on the hour consistent daily and Ca dosing during 10 hour on light cycle?
2. Dose both Alk and Ca for 24 hours each hour with a 30 min off set for one of the elements?

Your comments and recommendations are appreciated.
