[APD] Interesting BBA Observation

I have been very slow in putting together my latest tank, and so it has 
been running with CO2, no light, no fish, and no plants for a month or 
so. The water does have nitrate from using ammonia to trigger bacterial 
bloom. I noticed something strange ... BBA appears on the pH monitor 
probe (right on the glass bulb) and nowhere else. I cleaned it off with 
a toothbrush and it returned. Still nowhere else in the tank. This leads 
me to believe that there is something about potassium that BBA likes 
since the probe contains KCl as far as I know.

Anyone else have any theories or observations?
