Q: How can you allow for a pH range of 2.0 to 2.3 when conventional ranges sit at 7.4 to 7.8?A: The very question itself unscores our claim that the use of scalar wave technology applied to minute quantities of sulphuric acid and potassium hydroxide (to make H3O and HRx respectively) with incredible properties will be recorded as one of the major technological finds of the early 21st century.The claim seems fanciful -- and yet anyone with simple laborataory equipment can verify for themselves that our claims are justified. Consider this: You can take a fluid ounce (say 30 ml.) of our H3O at pH 0.2 and add it to HRx (at pH 13.8) and they will balance out with absolutely no exothermic reaction.That isn't supposed to happen.Ask any chemistry professor.In the case of H3O for Hot Tubs & Spas, yes, using conventional wisdom, our H3O, at a pH of 2.0 should be corrosive, to both human tissue, if not components of the spa itself (PVC plumbing, heater, pump, etc.) But the verifiable fact of the matter is that it is not.We know. We've had 4 years to test the product.Therefore, our recommendations should not be interpreted as contradicting the traditional advice of those in the pool and spa business. Maintaining an acidic pH that is under 7.0, will, in degrees as you become progressively more acidic, make for spa water that is corrosive. Their advice is correct. But that advice applies to traditional acidulents -- not H3O.That is one of the unique features of this product -- one that is readily verifiable by those who want to put our claims to the test.
