I just got the Alkatronic controller and plan to use that to monitor my alk. I see the controller also has a doser built in so it can dose alk to maintain the alk within the desired range. However the instructions say to continue using my current Part B doser and use the Alkatronic only to top off. So how do I do that? Do I need a separate dosing container with Part B attached to the Alkatronic? And do I keep my current dosing schedule the same?
