In my research I'm finding that people are using an assortment of compounds to add acid in the water for continuity. Some of these include Salt and Baking Soda..

In all of the examples and videos that I've seen, everybody just says the amount that works for them; then they say that it is a trial and error solution.

Does anybody know what the proper Ph balance is to draw 15 Amps?

Is there a ratio table, or, a formula that will will show how much amperage will be drawn at certain Ph balances with a certain quantity of water?

It seems that you can add anything acidic to the water to make the Ph balance go up? Could you also just use Ph Add solution.. Like the stuff they use for pools and fish tanks? Or maybe even lemon juice, or the acid squeezed from orange peels?

That seems like it would be the cleanest solution. And possible less corrosive than salt? (no crystals).
