I have been trying to ph my water using the General Hydroponics PH Up and Down. I put my water in a gallon jug, test it and it is usually high. Around 7.5 or so. Put ONE drop of ph down and test it. It goes all the way to the other end of the range. Around 4.5. Put ONE drop of ph up and boom. All the way back up at the high end of the range.
I have been using this method for about 6 months and I have always been able to dial it in.
Can this stuff go bad? I don’t know how to do half a drop. Lol.
