Salt Chlorine Generator Briidea Chlorine Generator for Hot Tubs & Swim Spas Up to 2000 Gallons Chemical-Free

• ...ANY HOT TUB TO A SALTWATER SYSTEM: This salt-based spa system convert the natural salt into pure chlorine work by electrolysis, then recycles the chlorine back to the salt, making it safer and more reliable than traditional chemical chlorine. The concentration of salt required is small, less salinity than tears.
• LED INDICATOR: Built-in timer/controller with LED indicators. It can run daily accroding to the time you set, no need to wait or setting frequently. The interior adopts unique detection method of salt concentration, and the LED indicator clearly indicates the level of salt, keep the salt in a normal operating range.
• LONG SERVICE LIFE: The titanium cell is the most reliable power system available. Our titanium cell will automatically switch polarity every 5 hours, prolong the service life, do not replace frequently, save your cost. Warm tips: you need to test chlorine weekly, adjust timer accordingly for great results, 1-year warranty.
• SAVE MONEY: Use our chlorine generator, you can save a lot of money in chemicals, save your time on not having to buy and store chlorine, make your tubs maintenance easier and more economical.
• EASY INSTALLATION: No plumbing required, plug in the controller above ground and out of water, while immersing the chlo....
