No doubt it's tough......
My tap water is 7.0 pH which is in most city water systems. To regulate this they use Chlorine and Sodium Fluoride. It is very hard to raise above 7.0 potential Hydrogen with tape water containing Chlorine and Sodium Fluoride. I don't have the pool testing equipment to prove it yet but I will. You can drop tap water like a rock with ease.... just add a little Gatoraide to it or any sports drink period. Add a little Gatorade and it will drop to 2.5 which is what Gatorade is.... 2.5 potential Hydrogen.
I will never ever even if I am dying... drink Gatorade again. It's poison.
Now I understand why when I used to drink Gatorade 2.5, Sodas 2.5, and Beer 3.5 I would get Acid Reflux.... the acid in my body was too high. I have not even come close to having a case of heart burn since I started drinking this water and that is just not possible... it is a every day thing for me. It means my pH is higher and less acid in my system. It is all I have been drinking besides beer. I am changing to Vodka.... zero hangover when you mix 9.0 pH Kangen water and Viodka or any clear liquor. My experiment for tonight. Anyone want to ooVoo watching me get drunk.
I will provide more info later... I have to run. Your question is not an easy one to answer so I have to gather specifics.
