Unbleached flour can work. It typically takes longer.
Whole meal, or other flours (rye and spelt notably) can really "juice" the process. Rye seems to strongly encourage starter activity.
Mixing even only 1/4 of an alternate (whole meal, rye, spelt) in with unbleached flour makes new starter development much faster, and can also help refresh an older starter.
