Tonight would be a VERY good time to "get a chance". You can be sure that otherwise, the algae will be "taking their chance"! If it 'blooms' it will me much harder (by multiples, not %) to clean up.

For a ~22,000 gallon pool, 6 gallons of PLAIN 6% bleach added in the evening would be a good dose . . .
