Should I leave CO2 on for the night?

I am currently fighting the BBA and my water parameter as follow:

PH: Set to 7 during CO2 on period, CO2 is on 2 hours before light is on to bring the PH down to 7. During the night PH goes up to 7.7 ~ 7.8 and I have tried aerirate the water over the night and the PH went up to 8.0

KH: 7
NO3: Undetectable
PO4: 0.02

My question is should I bring my PH down further to 6.9 and should I shut off CO2 during the night?
