Kalkwasser would raise both alk
and cal at the same time. It is a "2 birds in 1 shot". I would not dose baking soda once I dose with kalk
. I dose only with non baked baking soda to raise alk
and dose with cal separately. That way you can easily control the amount of dose for each. My 60 gal
reef tank consumes about 1 gal
per day of ro
with a mixture of 1/2 teaspoon of baking soda in my ato. Then I add cal if necessary to maintain it.
