Does anyone know how many public swimming pools in NYC use ozone for disinfection? Information appreciated!

I don't know, but I wish I had gone with the ozone system instead of a salt water pool for my own home.  I was talked into a salt water pool.  The salt precipitates on everything, hardscape, pool tile, equipment, and makes a mess.

 On the plus side, the salt water feels good on the skin.
