For your consideration: Hot Spring, Watkins, Replacement Spas Freshwater III Ozone System Complete #72602. I ordered this as a replacement for the original unit which I thought was going bad, but turned out to just be a clogging filter. Box opened yet never used; Just as new. This is great addition or replacement for maintaining chemical free sanitization. Thank you for your interest. This item is in the category “Home & Garden\Yard, Garden & Outdoor Living\Pools & Spas\Spas & Hot Tubs”. The seller is “cubbyg” and is located in this country: US.
