    I have some old pH up and down and i was wondering if
    it goes bad. I've had them for quite a while now, buts it's
    been a long time since i used them. The brand was
    General Hydroponics. Any information on this would be
    helpful.

    -Tnx

    ph up and down alters acidity. If it's not organic, it shouldn't go off.
