ph Controller vs CO2 injection night/day
Just received my CO2 tank with regulator, solenoid, etc..
I also purchased a controller... not sure if i will use it or sell it to my friend... i might give it a try.
I know CO2 should be started 30min before light on and shut off 30min before light off. Is this still applicable with the Controller ?
Meaning my timer plugged in the wall, and my controller on the timer ?? so it shut everything off during night ??
The controller only monitor ph/CO2 injection during day period ?
