Does the PG eventually evaporate or dissipate?

Eventually is a long time, and evaporate / dissipate the wrong words. in several years the PG will become less effective due to reactions with contaminants in the air (er, like tobacco smoke for instance )(G&D). I recommend changing it ever year or so because of this phenomena. Using the same PG for 3-5 years with just water replenishment is not uncommon however. If your credo isn’t regulating the environment like it used to, it might be time for a change. A common problem causing loss of PG is over-watering when recharging. Any water which runs through your credo is removing PG as it runs out! Careful re-charging will avoid this. • I just made a credo and my humidity’s too high! A new oasis will take days (up to a week) to stabilize. This is because PG does not regulate through partial vapor pressures, as the salt test does. PG regulates through a tenso-active (surface tension) process. The PG and water do not create a solution, it’s actually a mixture (with seperate components). The
