Help me with my humidor!

I'm not using the beads. Are they an add-on or substitute for the humidifier? I am using an analog hygrometer that came with the humidor. I cracked the lid open for a bit and that seemed to help lower the humidity level. I only used maybe an ounce of distilled water when charging the humidifier (it is the small round type). Will this be enough to keep the humidity level stable. I took the cup of water out too.
