I started dosing kalkwasser earlier this year with a single dosing pump. Love it, but as everyone says, this only takes you so far. I am at the stage where I need to supplement with 2-part. Here is my question. Can either part of the 2-part solution be dosed from the same water that contains the kalkwasser? My plan would be to dose one part from the kalkwasser solution and the other part from the top-off water. The fact that I haven't found any information on this probably means it won't work but I thought it worth the ask. Thanks for your thoughts.
