The green foam type humidifier are meant to be used with PG solution. All you are doing is adding moisture, that is why you are reading so high. There is nothing to regulate humidity. PG(propylene glycol) will regulate to 70%. You can get beads that will regulate to 60 or 65%. As the others have suggested a digital hygrometer will give you a more accurate reading. But you need a humidifier that will both raise and lower humidity as needed.
