Odorless if used with Oxy-Spa (potassium monopersulfate) non-chlorine shock. Makes your spa so easy to manage.  Assures an odor-free hot tub, while significantly improving the look & feel of the water.  Simplifies water balance since it releases its sanitizer automatically. 9 out of 10 spa users prefer Nature2 over their old method! Improves performance of ozone-equipped systems.  Suitable for spas up to 500 gallons. Easy Installation: Drops into the core of most spa filters.  (Works with suction-side and pressure-side filter systems). Run spa at least 4 hours daily to release and disperse mineral ions into the spa water.
