All For Reef calcium increase and alkalinity decrease

[Tami7878]

Hello. I have a total water volume of 43 gal. I perform weekly 5 gal water changes with Red Sea Coral Pro Salt. My alk consumption is about 1.2 dkh each week. I began dosing Tropic Marine All For Reef a little over a month ago, following their suggested amounts for a lightly stocked tank. It seems my calcium is continually increasing, but my alkalinity continues the same decrease. Per Tropic Marine's site, in some cases the element consumption may vary and to follow the chart shown to adjust alkalinity. The chart suggests that I reduce All For Reef and begin dosing Balling B. May I please have some advise on how much B I should dose in conjunction with AFR to keep my alkalinity stable?

Any alk supplement, such as baking soda is fine. They just recommend their alk product because that’s what they provide.

here’s a calculator to determine how much is needed:
