I just wanted to update this thread to share one important lesson I learned. My test kit was totally wrong. I have since learned how to calibrate Kh and Gh test kits and both were off by more than 50%. So based on that, I am not longer sure I should have quit dosing Mg. My Kh and Gh are actually 6, and 7 degrees.
