The pads definitely make the humidity stay much more consistent. I also run the 56ex. Use em and buy humidifier pads off amazon to cut and replace when needed same material. I've ne never had humidity problems except when I thought I didn't need the pad after they were used and dirty. Sponge is ok but not porous enough as the air flows through the pad increasing evap off the pad. Wish you luck with your hatch!
