For the longest time we could not figure out why pH testing strips always leaned on the low side when testing alkaline water. Almost without exception when someone contacts us to say their system isn’t giving them a high enough pH, it’s because they are using strips to test the water. When they use drops that change the water’s color, it immediately registers correct.
The answer lies in understanding that pesky difference between pH and alkalinity. Strips are made for testing body fluids and all of our fluids are of the “buffered” variety. Buffered simply means it has a concentration of solids in the water. Things like electrolytes, salts and other mineral compounds constitute the buffering material. The concentration of which matches up and supports the pH.
With alkaline water, depending on how it’s made, there is a gap between buffering material and pH level. With electric systems, that gap can be pretty large. Which is why the pH level can crash pretty quickly after removing it from the electrolysis. With natural systems, that gap is typically less resulting in a water that declines slower and is more gentle on the body.
The gap is smaller, but it’s still not completely balanced with the mineral content. The reaction between water and magnesium we use to create the pH, hydrogen, -ORP, antioxidant levels, etc does cause the pH to rise above the alkaline level.
That gap causes the strips to be inaccurate when testing the water. Which means we need to use drops to test our water, and strips to test our bodies.
Hope that helps.
