Hi all,

I have two dry fertilizers and I´d like to understand how to calc the correct amount.

Yara Krista K:
12% Nitrogênio Total (N)
45% Potássio (K2O)
1,2% Enxofre (S)

Yara Calcinit
15,5% Nitrogênio Total (N)
19% Cálcio (Ca) hidrossolúvel

I was trying to use the following link to calc, but all online calculatores give me others values:

I´d like to mix in 450ml water, dosing 1ml to reach 1ppm(N) in my 65liters aquarium. Two solutions bottles, one for each fertilizer.

thanks a lot.
