Having trouble with PH increase/dosing pump

I am having trouble getting the GHL to control both the Cal Kal reactors.
Cal seems fine the second ph probe is working fine inside the cal reactor and maintaining the ph with the CO2.
The first PH probe is in the sump and should increase the PH via the Kal reactor that is feed by the dosing pump. I should be able to control the dosing pump with the first ph probe ?

i hope this is clear
thanks redfish
