Unexpected alk jump

My alk just increased by 1.0 dkh over five days or so. I've been carbon dosing for awhile now because of my high nitrates. Would this cause my alk to increase if the bacteria is consuming my nitrates? Nothing has changed in the amount I dose for alkalinity. Went from 8.8 to 9.8 dkh . Usually the alk drops a little or is fairly steady.
