When should I use the water pen, and can tap water be used?

Use the water pen when the app indicates poor sensor contact or during the sensor check if signal quality is low. A small amount of water is sufficient. Ensure you are applying water to all of your electrodes; this improves the connection by increasing your skin's conductance. It can help to do a session after a shower to remove any products/oils from your hair, and while your scalp is slightly damp. Tap water (potable/municipal drinking water) is recommended.
