The MBP Troubleshooting Chart functions as the organizing tool for the program. You will be using a new chart every time you do the Microbial Balancing Program, often using multiple charts per issue, and you will be doing a lot of writing on it. There are 50 loose-leaf, 3-hole punched blank charts per pack. A blank chart is printed in the Manual. Or download a blank MBP Troubleshooting Chart for free here and print them as needed.
