How much ammonia to add

[J1000]

Hi all, I wish to cycle a new tank by adding ammonia. I've run the math but wouldn't mind if someone else were to confirm or deny my numbers.

I will work in litres here. So it's a 160 litre tank and I have 10% ammonia solution. I wish to add enough solution to the tank to create 4 ppm ammonia. My answer is below is 6.4 mL.

That's what I got from the "Fishless Cycling - Ammonia Required"
