The BBB water gets "sparkly" like nothing else.

Borates made it even more sparkly. But that is a completely different process.

2 cutie pies swimming and might I say too, your water is 'sparkly sparkly'

Well, you too can have even more sparkling water for the price of about 10 boxes of borax and 3 gallons of muriatic acid. You can look around here for the process of adding borates to the water. Something to keep in mind if you ever get bored with your Trouble Free Pool.
