  1. how do i do this?

    say, my pH of runoff is 7.0, how would i calculate what i need to do, if say, i wanted to lower it to 5.0?

    this is all theoretic, i havent tested anything yet, just need a formula to calculate how to raise, lower?
     
  2. Why 5?
    Just water it with water that has a ph of 5.
     



  3. it's just solution with a pH of 5.0, i understand how pH works, i guess i can only really experiment, to see how much of each solution lowers the pH of a gallon and go from there...
