I bought an ozonator from Dr Katz (you can search Katz ozonator and find it). It was around $130 I think. I drink the ozonated water, so does my dog we both love it (separate drinking vessels LOL).

Back to my bath. I ozonate a gallon of water for an hour, meanwhile I fill the tub a little hotter than needed, it gives the chance for chlorine to start to evaporate. When my ozone water is done I pour that in the bath and use the ozonator directly on my bath water while I soak. First time I used it I didn't want to leave!! I've even gone so far now to nearly submerge. My scalp and hair feel great!! I've done this bath alone or with epson and baking soda.

The other added benefit to the ozonator is that the room I run it in is so much fresher (I move the machine from room to room for this added benefit).

You can buy a whole house water filter pretty cheap OR you can buy that chemical that you put in fish tanks that dechlorinates the water before you add the fish, that's Really cheap!

Although, I've read that adding Epsom Salts and baking soda "decontaminates" the water all by itself.
