Cycling whith NH4Cl

[pedro]

Good afternoon I'm going to start a new tank and I'm going to dose NH4Cl to help the cycle, something I've done in the past
but I lost my schedule someone can tell me how to do the mathematics of how much NH4CI I need to raise the ammonia to 4ppm in 250lt
without being here in the forum but can not find
thank you
best regards

The general formula for PPM calculation is (contextualised):

dose / water volume * 1,000,000 = PPM

So:

1ml / 250,000 ml * 1,000,000 = 4PMM (assuming purity, of course)

Is that what you are looking for?
