That's alot of potassium.....too much in the blood stream will cause cardiac arrythmias which can be fatal...also there are many forms of potassium...chelated, different salts of potassium whic will affect uptake and concentrations.
I agree that ph is very important, potassium is important, sodium is important but to suddenly take this much potassium in lie of other candida treatments that don't have such risks...well, sounds a little frightening to me...
