Conical Woes

Satan sent me an email about our conical woes: ". . .read below….does that sound familiar?
"Acetobacter: Oxidizes ethyl alcohol to acetic acid, creating vinegar. Aerobic or micro-aerobic-must have some air. Tolerant of hop resins and low pH. Forms tough pellicle. Most common in lightly carbonated draft beers.
"Causes acidity, turbidity, ropiness. Forms a greasy looking pellicle on the surface of infected beer. Easily prevented by excluding air-keep carboys full, or flush with CO2!
"Too much head space perhaps?"
