Aside from the PH test, none of the others seem to be checking anything. We developed different solutions with different chemicals to see how they would change the test results - absolutely no difference. Complete scam. Pond water, well water, tap water, iron-saturated water, copper-saturated water, vinegar, etc. Only PH showed a different color. If you want to be comfortable with tap water, use them - they show you that everything is fine. Otherwise, if you want to know what's really going on, don't waste your money on it.
