The dark liquid is a drop of Betadine in the airlock. When moving the 5 gallon fermenter, liquid is often drawn back into the fermenter, and this should be sterile.
Completely agree about the whole sterile solution in your airlock. Personally I never bothered. I was lucky never to have contaminated my beer (I used tap water). Nowadays I am fortunate enough to have a dry airlock which uses a tiny ball which as the CO2 escapes the ball floats. This then drops causing a lock. Very clever idea
Anyway, instead of using Betadine, why not try a little vodka instead. This way you get to drink the contents of your airlock afterwards :beer
