Hmm mine takes about the same, but the ph up takes about the same as well. There's a lot of minerals in the water that act as a natural buffer.
JackdaWack Reviewed by JackdaWack on . General Hydroponics Ph Down My well water has a bit of mineral content, including sulphor. The Ph is 7. I used a chemical Ph tester and found that it took about a capful/gallon of GH Ph Down to go down to 6.0. Doesn't that seem to be a lot of Ph Down? Thanks for your feedback. Shov Rating: 5
