Blacking tank out, should I turn off CO2?

Hello all, blacking the tank out for a few days around the holidays because I won't be home to enjoy it and I do have some filamentous hair algae I would like to stop. Do I turn my CO2 off?

I am guessing I do because photosynthesis will be slowing way down without lights. Only reason I am asking is because I don't want my PH to change over the few days.

TIA

Absolutely. Your co2 should never run when the lights are out. Ever. Like not even at night.
