Nature² Spa cartridge works
with your existing filter to give you clean, clear water without high levels of chlorine. A difference you can see, feel, and smell.

Nature² SPA works by automatically dissolving trace amounts of mineral elements into the water. Those elements act as a sanitizer to destroy bacteria and viruses. Just drop the Nature² SPA stick into the spa’s filter and forget about it for up to four months! Nature² SPA will keep your spa sparkling clean and smelling great ? even in-between use.
