Kalkwasser reactor needed?

[Morgosverlo]

Do I need a reactor or can I pump kalk mix directly from my resivoir. I would be using a Milwaukee PH controller for the pump or I can hook it up to my Tunze ATO?

I also have this Bubble Mugus. Tired of manual dosing/ Pswings and just want to be able to do something auto with what I have. Thanks for any help in advance

The green pump on the wall is hooked up to the Milwaukee Ph controller.
