Dosing ph swing question

[anen]

I am using Randy's 2 part with BRS dosing pumps. I have the pumps set to dose for 15 minutes for every hour, between 1am-5am. (Obviously cal and alk are staggered) When I look at my ph graph on my controller, this is making the ph swing pretty rapidly, from 8.1 to 8.3, and 8.3 to 8.1 fairly quickly. Will these short and rapid swings negatively affect my tank inhabitants? If so, can you suggest the best dosing schedule for me?

When do lights go out and on? Can you not spread out more over a longer period so it does not swing as much?

you could break your 1 dose up into 3 or 4 small doses though out the day.
