Hi
You can call 407-226-3705 These people sell the Alkalizer, they are slow so I call every day until I get an answer. I bought some 02 from them Also go to www.ionmicrowater.com
The Melody is the best, the Alkalizer Co. customer service is very slow.
If your body is alkalized, cancer cannot live there. email me if you need to. beaverex@quik.com
