so i did a runoff test with tap water n it came up as over 8.4 my tap water has a very high ph could this be the problem? i dont know if i got an acurate reading because i tested the tap water on its own after and it looks pretty much the same as the soil runoff the alkalinity is was also very high over 240 ppm these test strips sat outside all winter and it says store at room temperature so i duno if its acurate at all now
