Using Biofine powder

[bsimaz]

I purchased the Biofine P019 and I'm looking for some help. I've read that usage is 300-700 mL per 1 hL. (from BSG).
My math says that I need about 5 pounds for a 5 bbl batch using about mid-range usage of 500mL per 1 hL.
I purchased a 5 lb bag but it seems like that is a LOT of Biofine.
Has anyone used that Biofine powder and could give me some help in dosage and method of use.
Thanks,

You are supposed to mix 1kg of powder to 200 liters water for your stock solution. You then use the 300-700ml per hL out of the stock solution.
