While descending through about 9;000 ft.; both pilots experienced a very strong magic marker / chemical / fume smell in the flight deck while the Flight Attendents (FA) in the forward cabin smelled a musty / dirty sock / fumes event smell. The FA's in the back did not experience an odor. It came on quickly and quite strong. We donned oxygen and quickly performed the odor recognition and isolation procedure from the manual. Turning Pack 1 off seemed to correct the problem. All necessary logbook entries were made. All necessary reports filed.
Air Carrier flight crew reported a fume event during descent. Flight crew completed the procedure in the manual which corrected the problem.
