Dosing Alk and calcium via doser

[brownsalt92]

Hello so I've had my dosers on my 90 sps tank for a week. I have 2 brs 1.1 ml dosers for soda ash (alk) and calcium chloride (calcium part)
I do weekly %10 water changes.
Params are
1.026 salt
Temp 79-81 with a chiller
Mag always 1350
Calcium at 420
Alk 7.7 dkh
Mainly sps with a 3 inch derisa clam

Do I need to try and dose evenly I'm uo to 80 ml of alk and still won't raise above a 7.7 salifert test kit
I dose 65 ml of calcium and it stays at 420 the more I dose. For both they still stay even api test kit... I have a salifert but...
1. Will salifert ca test still be fine to use after the third part thaws out?
2. Do I need to dose evenly for the calcium and alk or is it common to dose more alk than calcium?
3. I dose from 20:00 until 10:00 via apex and brs dosers should I be dosing all day instead? I dose during the night to keep my ph swings from getting lower than a 7.8.

You should dose even amounts

You should dose at night but dose separately CA and ALK right and at different times? Correct?

I dose at night alk at every 30 calcium at every 00

You should dose even amounts

Even if it's not 2 part like 2 little fishes part a and part b

Dose equal amounts at night. Wait 3 days and check alk if it is coming up increase the dose ( both cal and alk) until you reach your desired level

So I dose 85 ml alk now and backed my calcium down to 70 ml. The alk test at 7.5 dkh desired level is 9
Calcium 470 now amd desired is 450.

What should I do?

Should I raise the alk to 9 with 2 part or a buffer and see if it will hold that level with the amount I'm dosing?

My understanding is you keep dosing equal parts until your alk reaches your desired level. As alk goes up more calcification occurs and will bring your calcium into balance.
