If in fact you do have a pedio infection (wondering what makes you think you have one BTW?), then you will most definitely have to pitch some brett to clean up the diacetyl that the pedio will produce over time. Otherwise the beer will become a rancid, butter bomb. At this point (if you are convinced it is pedio), then I would probably pitch a couple bottles of sour dregs, and rack it to a carboy for extended aging. It will probably turn out pretty good given 6-9 mos or so.
