It takes quite a while, not minutes or hours. You can't set a pan of distilled water out and check it the next day and it be different. It would have to leach from the physical "hard" environment, in this case a pan, which would take days to months. Or you would have to have a dissovable substance, like a powder or tablet, for example chlorine. Or you would have to add a liquid or have extremely high humidity, which humidity wouldn't be that fast.

The reason my pool changes Ph, etc, is the sun burning off the chlorine, evaporation, and rain. Only the rain makes a fast change.
