Alkalinity and Calcium

[dtracy1119]

My reef tank is just about to be 1 year old and i recently, 2 weeks ago, started adding coral (LPS & SPS). The alkalinity and calcium came down alot this past week. dKH was 7 now it's 4. Calcium was at 420 ppm. Now it's 360. I was wondering if I can use baking soda to raise the alkalinity and continue to use baking soda to maintain it. For calcium I have Seachem calcium. Will I be ok to use these???
