Chuck's Planted Aquarium Calculator Question!

[DaveW]

I have a little question about the Chuck's Planted aquarium Calculator. I what to calculate the amount of nitrate I need, but on CPAC it has 2 nitrates which are both KNO3.

First is Nitrate in Potassium Nitrate (KNO3)
The second is Potassium in Potassium Nitrate (KNO3)

I believe it is the first one, Nitrate in Potassium Nitrate (KNO3), but I want to make sure before mixing up another batch.

Cheers
Dave

PS: I have Potassium Nitrate from Aqua Essentials.

In the first one its measuring Nitrate in the Potassium Nitrate (KNO3) whereas the second one is measuring the Potassium in the Potassium Nitrate (KNO3).

I see, if I what nitrate, then it is the first one I need!
