AnD,
I use the premixed 7% HTS with my Eflow. If I am correct, to get the Eflow, we have to order Tobi through their company BUT, we get free HTS shipped with Tobi orders.
For anyone who has not tried the HTS, let me tell you this - BE PERSISTANT! It is possitively gross at first! Gagging, even. But if you persist, if you build yourself to get through the whole thing, it is the GREATEST!!! I was on Hospice last year when I started the HTS and I believe it helped. ( God is the reason I survived but He used SALT WATER to do it!!! Ha! His own creation, can you believe it? )
So bear with it and you will feel awesome afterwards. Any questions about the stuff, just ask!
