| | | With over 50 years of experience, Jacuzzi is the leader in hydrotherapeutic innovation. The ProClear Water Management System in the J-300 Signature Collection is an industry benchmark; the culmination of decades of testing and improvements. It ensures clear water with minimal chemical maintenance, and low operating costs. Patented high-volume, energy-efficient technology includes an efficient 24-hour circulation pump (water in motion is cleaner water). Self-activated purification keeps plumbing components clean and niters surface particles, even when the spa is not in use. All of the 2007 J-300 models include a new and improved niter shield, as well. Add bromine or the ProClear Natural Purifier (options) for water purity that lasts longer. | | Tri-Fusion System Shell Three layers are combined for strength and durability: Beauty-a seamlesssheetof durable acrylic in long-lasting colors.
