Ozone reduces the amount of shock needed in an Bromine sanatized spa.

As Bromine dissociates into Hypobromous Acid, and Hypobromite Ion ( in the presence of inorganic, and organic contaminates ) It kills, and oxidizes.
The problem with Bromine is that it's Ion is weak, and doesn't burn up inorganics, carbons, etc. This condition causes Bromine to form a compound known as a "Combined Bromine", or "Bromamine". This "Lazy Bromine" doesn't sanaitze well, and eventually will tie up the free available Bromine in the spa. The spa industry ( no doubt embarrased by Bromines shortcommings ) decided that the general public was incapable of shocking their spa water as part of a regiment of spa care. Thus the constant oxidizing of Europes miracle gas was adopted. Your '95 "Ozone Ready" LBI is not Coronal Discharge ready. Without a Mazei Injector, it's useless. Leisure Bay has provided a "J&J" plug configured receptacle outlet, with a capped off "Euro Jet" Air tubing. A two speed pump means that you will be introducing Ozone during heat, and filter runs only.
Hardly worth the trouble. IMO
