No, it will not impact calcium.
it may impact demand for alk and calcium going forward, but an alk addition has no immediate impact on calcium.
There is no "normal" for alk swing. Daily alk demand is usually 0.5 to 3 dKH per day. The swing varies with how often you supplement. I'd try to keep it stable within a 0.5 dKH range.
So I have been using the calculator that you suggested to dose the Alkalinity. Originally I started with 7.46 Alk. According to the calculator I need to dose 15.6ml of Alk to bring it to 8 dkh.
On Aug 31 at 11pm I dosed 7 ml.
Sep 1 at 3 pm - Alk showed 7.63 according to Trident. I then dosed 8 ml more. At 7 pm, Alk showed at 7.91 dkh.
Sep 2 at 9 pm I dosed the remaining 0.6 (total of 15.6 ml).
Sep 3 - after I replaced the Trident Reagent A, Alk showed at 7.84 (it came down?). I used to the calculator again, and dosed 4.6 ml to bring it to 8 dkh.
Now the Alk is showing 7.95 dkh.
Why I didn’t get 8 dkh after I completed the 15.6 ml dosing? Should I continue to use the calculator and dose again until I see 8 dkh?
