What is alk Cal

I use rowaphos and brought po4 from. 16 to. 08 in a week without issue.

I did have one acro stn a littlqe but alk. Was 6.5/7

I added 1/2 cup but my phosphates were low already so I don't think that couldn't have been the issue.
I keep my alk at 7dkh since I carbon dose and calcium around 420-430

I used it in a reactor and I rinsed it through the reactor with r/o until it ran clean. I even added a sock on the output ofthe reactor just to make sure any particles dont get into the tank.

This one has got me stumped......lots of threads online about this but none with a "proven" reason
