Leslies is recommending "alkalinity Up" see test and my subsquent check with my strips.

IIRC, i can use Baking soda in lieu of their house product? what is the measuring methodolgy for adding baking soda? is there a rule of thumb?

I don't usually have to address alkalinity, would could have potentially caused it to be low.?
