How do you reduce diacetyl?
Diacetyl is controlled by allowing yeast the time to assimilate and metabolize it. Using time and temperature, a brewer can control diacetyl. At higher temps the oxidation of alpha-acetolactate is more rapid and given adequate time the yeast will reduce the amount of diacetyl.

Unfortunately, there isn't a lot you can do apart from wait and hope the diacetyl levels decrease.
