pH Calibration
Is there something that anybody knows of that has a particular pH reading? I do not have any more calibration liquid until I go out of town to get it but need to calibrate my pH tester now.
Someone mentioned one time something about mineral water being a certain pH, but have forgotten what it was.

I would not mess with the ph cal until you have some 7.0 =} best to wait.

I broke my Ph tester (the glass bulb) I was stoned and well sloppy I guess. I just laughed until I realized that I now must replace it. So I am going to call hydro shop and ask for a replacement part.
