Potassium Test Kits ?

[Reefer Rob]

I've wondered the same thing every time I try to use the KZ kit! The solution is so murky, you can't even see the line at the darkest end. If I dump out half the solution and re-fill it with tap water I get a reading of about 350. I wouldn't think my K is off the scale high since I've never dosed any K additives.
