Jet-A loves water and allows bacterial growth. Prist, in addition to being
an antifreeze, is an anti-bacterial.

Of course, Prist can no longer make this claim because the EPA has made it
commercially prohibitive to certify something as a pesticide. It's officially
an anti-icing additive...if you no longer have to worry about crud growing in
your fuel, all the better.

While bacteria will grow in the fuel, it's actually fungus (Hormoconis Resinae)
that's the real problem. It's not just the water but the fact that this bugger likes
to eat the fuel. The bacteria tends to stay with the water and thus is removed
by the normal water traps...and filling up with fresh fuel alleviates the problem.
The fungus likes to hang out on the surfaces in your tank and you'll continue
to have an infestation until you actively put something in to kill it.
