Converting from kalk to 2 part

[spscrackhead]

I get the rest of my supplies to run 2 part on Friday and was looking for some suggestions on how much to dose.
The tank is a 175 with 30 gallons in sump. I currently mix 6 heaping tbsp of kalk into 11 gallons of ato. This top off lasts a bit less than a week. I would say I have to refill about 6 or 7 times a month.
I have 3 brs dosing pumps that will be hooked up to u apex. One for calc, one for alk, and one for mag. I would like to keep the Ph stable, so dose the alk at night. What would be good starting dose be? If anyone has good apex programs that would be great as well.
Thanks!

A rough equivalent starting point is 200 mL of each part of the two part each day.

Hm, I wasen't expecting so much, seems like a lot.
Also, Is it general consensus to dose alk in the PM and ca either 24 hours or just PM to help with the PM PH drop? Or am I over thinking things like I tend to do?

I dose alk throughout the day with offsetting doses of cal. I still dose some kalk to keep things stable. I dose 45ml to keep my alk at 8 for a 150 gal tank.
