Drymistat tubes

I am looking for some help. I am somewhat new to cigars and am very new to humidors. I recently bought an acrylic humidor jar with a hygroset II hygrometer. I calibrated the hygrometer but have tried using drymistat tube and xicar jar and have found that these products make the humidity level go far over 75%. Does anyone have any suggestions as to what humidification system I should use in the jar?
PLease help!!!
