Baking Soda

Baking Soda = Arm & Hammer (generic may be OK) but I use A&H.
Using leveled TSP measurements this what I think I get with it.
1/8 tps/6.65gallons of water = 1dKH
1/4 tsp/13.21g = 1dKH
1/2 tsp/26.42g = 1dKH so you can figure your volume from there.

2dKH usually tests as 6.8-7pH
3dKH = 7.2-7.4pH
pH readings are water w/o CO2 injected.

I generally use the 1/2 tsp increments for me or doubled to 1 tsp.
Added at water changes I don't see a need to add more.

Baking soda will make your kH rise.

Baking powder will make your cupcakes rise.
LOL! Thank you for that laugh. :)

Baking powder is baking soda premixed with a dry acid, so that when water is added, they react and produce CO2 bubbles (rising your cupcakes). It also contains starch and possibly other additions, to absorb atmospheric humidity which would cause it to prematurely react in the can, and to keep it from clumping.
