Your hot tub is great at keeping itself clean. Whether you use a chlorine, bromine, ozone, or salt water system to purify your spa, you enjoy pristine water, free of contamination, for months on end. With every system, you’ll need to change the spa water now and then.
If you use a traditional chlorine or bromine system, you should change the water in your spa about every three to four months. If you use the FreshWater Salt Water System or ACE Salt Water System, you’ll need to change the water in your hot tub a lot less often—just once a year.
