has anyone tried non-toxic hot tub maintenance kits?
We are looking into putting in a hot tub, and have been looking at the non-toxic alternatives to the common hot tub chemicals that are used. Does anyone out there have any personal experience with any of these? For instance, "Ahhnatural" brand natural hot-tub maintenance? We haven't been able to find any 3rd party reviews of this or similar products outside of the words of praise that the companies list on their own sites. Thanks for any help!
