I am starting Vodka dosing in my 250 liter tank (about 65 gal). I am using an automatic doser by Grotech which has the smallest unit as 1 ml. So I diluted the Vodka with water to 10% of alcohol per volume and plan to dose it that way.

My question is: Will the evaporation in the dosing bottle (which is not airtight) change the percentage of the alcohol over time? The dilution is probably not making a difference, but it is going to evaporate one way or the other.
