where do you have your ph controller set for ph in your tank.
I am using a Milwaukee MC122 controller with a Milwaukee MA957 CO2
Regulator on a 10lb co2
I know you want the desired level of co2
in your tank so everyone settings may be different but I just wanted it for a reference to use with mine.
I am using a drop checker.
also let me know if your are dosing 24/7 or a set amount time.
