My calcium reactor is working!!!

[this is me]

Finnaly!!! after about 3 weeks of frustration the reactor finnaly starts to work.
I found out that i set my ph controller hi-setting and low-setting too high, so that my CO2 only injecting in the reactor haft of the day. I finnaly dont have to dose the tank for like 3 days now and the parameters stay the same.
Right now, my tank PH is 7.80 at night and 8.06 during the day.
ALk is 12dkh
Calc is 420ppm
Magnesium is 1290ppm
I know my PH is a bit on the low side, does this cause any problem? I'm running reserve photoperiod and my sump with a little macros. if i put more macros in there will it help with the PH?

if you dose kalk at night it will help keep the ph up

I tried that, but that raised my alk to about 15dkh!! i dont think i want it that high.

I thought kalkwasser is a balanced supplement so you shouldn't get too much of one or the other?

well, after testing my tank alk and it was 15dkh, i tested out the kalkwasser and the alk there was over 36dkh!! and ph was about 12. I dripped it fairly slow, slower than my tank evaporates. So i stopped dripping.
I was able to get the Ph in the 8.0 during the night and 8.2 during the day.
