The MBP Phase 1 Testing Process is the simplified testing that allows you to get through the learning curve of the Microbial Balancing Program easily, while at the same time get needed relief for your microbes. You will be using a new chart every time you do a Phase 1 test. There are 50 loose-leaf, 3-hole punched blank charts per pack. One blank chart is printed in the Manual. Or download a blank MBP Phase 1 Chart for free here and print them as needed.
