Bobby you might have a chance, but as for me I can see the two going together but still dont know the language. Others here have posted with good things to say, dosing through the osmolator sounds good.

As the Ca reactor is being controlled by the controller would'nt it not be mixing the two so much. At times they might be but could place the Kalk topoff away from the CA effluent. One close to the return line input the other to travel trough the sump & then return.

The osmolator is very precise it doses for like 10-15 seconds at a time. Would this change the way you think they react to each other.
