Using baking soda for alkalinity

[Tangina20]

I’m new to dosing my alk is 7 and calcium is at 340 , I bought calcium to dose and saw online you can dose baking soda for alk. I’m having trouble finding a ratio per gallon in order to raise it to 8-9.

Check out this link. I will be using this when I get to that point. Disclaimer: I've never had coral before.

Bicarb is ~30mg/L for a 1dkH increase. So for 100L your looking at 3000mg or 3g.
