Hagen test for KH

It will help raise pH a tiny bit to boost alkalinity, but more importantly, the way that you routinely boost alkalinity can also be a way to boost pH (like limewater or a high pH two part additive, for example).

Hi, I stopped adding baking soda ( Alk is approx 130 mg/L right now) because my CA is now done to 260! It has been suggested that I can add my Reef complete & Baking soda at the same time. I have looked over a lot of the links you have given me but chemistry is all Greek to me. Could you tell me approx how much of the Ca and Baking Soda I can add at the same time? Is this the right thing to do?

When you say at the same time, that is Ok in the same day, but I would not mix them or add them at exactly the same moment during the day. Let one mix into the tank water well before adding anything else.

This calculator shows how much of additives to use:
