Re: [APD] CO2 revelations

Can this be right?

That means to raise the KH by 1 degree in 200 liters of water you need to
add 6kg of NaHCO3 (300g x 200liters / 10)?

I think there's an error here somewhere...

If it's measuring CaCO3 equivalence, measure out 300g of NaHCO3 into 1 
liter to get 10°dKH.
