We must have stronger stuff up here or I just don't know.

half cup (125 ml) 35% for 10 gallons
+
1/4 cup ( 62.5ml) 35% for 5 gallons

Is that right according to your formula?

This 35% h202 I picked up today says to mix .5 ml per liter which in the end work outs to 28.5 ml instead of 187.5 ml using the other method.

OR is it just Canadian, American differences in measurements.

OR..just MADNESS!?lol
