It is merely Cal-Hypo powders, at 73% strength. Nothing more. It will consistently increase the calcium level in your pool, and when that calcium gets too high it will cause scaling and cloudy water. Everything else about the ad is hype. Also Cal-Hypo at that strength must be used VERY carefully and any contamination by other forms of chlorine, except when dissolved into the pool, can be deadly dangerous.

We have many discussions here of the uses and value of Cal-Hypo as a chlorinator.
