It's all in the tweaking. Takes awhile to dial it in. Just keep testing ca and alk every week.
I remember when Christy was first setting up her OA reactor she said: "Oh, there isn't a knob for turning it to... say... 400ppm, well then how do you dial it in??"
I don't know if she was joking or not
Just kidding Christy. I know you were... I hope.
