printing support structures

Using Creality Slicer v4.8.2-237 with Ender-3 V3

When I add supports for overhanging geometry the support prints way stronger/denser than the part itself. My support density is set at 20% but it’s infill it far denser than the part infill.

Can anyone guide me on how to lighten the supports? They turn a 2hr print into a 5-hour print. They are coming out almost solid.
