Distilled water has no trace elements (zinc, sulfur, phosphates, copper, sodium, iron, etc.) unlike tap water and a neutral pH. It's pure water. I bought a pH pen from Amazon for $24 and works perfectly. No need to buy complex pH tester w/electrodes for over $50-$100.
cool09 Reviewed by cool09 on . Question regarding PH level I've read that the water I use should have a PH level of 6.5 Can I use distilled water? Otherwise how do I determine PH level? Also, how do I determine the PH level of the soil? Rating: 5
