OH! You're right...I didn't realize that post was so old. Well, it took me awhile, but Spa Magic is still in Canada. It changed it's name in the US & is now called The Natural Hot Tub Company Water Treatment & Conditioner. It's exactly the same as Spa Magic & is sold @ xxxxxxxxxxxx.com
I'm also looking into: The Natural Solution Email: ryan@xxxxxxxxxxxx.com to see how the 2 compare.
I just know I cough so badly in my tub, I don't want to get in it anymore.
