I have been tempted to try Eco One or The Natural, which Doc sells. Â It seems to work just fine if you use a little dichlor with it. Â Chas experimented with Eco One a while ago with daily reports on the Doc's forum, if I remember correctly. Â Chas sent Vermonter a water sample to be analyzed. Â Again, if I remember correctly, the water was fairly pathogen free, but not as much as a chorine tub. Â That is why I believe a little chlorine is necessary.
There are enzyme users that swear by the product. Â It is supposed to be easy on your skin, smell good and easy to use. Â Three reasons why I have shyed away from trying it are extended filter times, weekly rinsing of filters and high pH (it likes a pH of about 8 which just seems unnatural to me).
