Alkalinity 2.0....I give up.

lol, ok, now I get it. :)

Any tips? Seems like it may be more stable but I need to get alk up. I'd the baking soda method ok?

I’d use the two part you have unless you detect precipitation in hardening sand.

Should I increase both alk and calcium at the same rate?

I feel comfortable raising it up to 0.5 dKH in a day. I’m not sure if there is a commonly accepted rate.

I have had my Hanna Alk reagent go bad, and read persistently low. When I got a new bottle my alkalinity was 3 dKH higher than I thought. Consider a backup test method or new reagent bottle to be sure

I’d stick to dosing them equally based on alk demand unless calcium is already too high or too low.

Yes, thanks Lasse. I have been storing it in the refrigerator for a while now.
