Separate timers for co2

Are there any benefits running the lights and Co2 on a separate timer? I was thinking on Starting the Co2 30 minutes before the lights turn on, and turning the co2 off 1 hour before the lights go off.

I read that some people do this, and wanted to know if there was any benefits to this method at all.

There are benefits indeed.

When you turn the CO2 on before the light come on, the water is already filled with CO2 when the plants start photosynthesizing.

When you turn the CO2 off before the lights turn off, the plants use up the remaining CO2.

This also helps with pH fluctuations I believe(?)

If I start Co2 30 minutes earlier, would it effect the shrimps I have in the tank?

No it won't, and if it does, it means you're efficiently diffusing the CO2 into the tank and might wanna lower your BPS
