I've used Nature 2 before and it does require using some chlorine as well - http://www.nature2.com/about/. It works fine, but once again, you're using chlorine which I'm attempting to avoid if possible.

Curious, what sort of health issues? Side effects? Flu-like symptoms, eye inflammation. I've spent a life time in the stuff. I feel like I'm a human guinea pig for chlorine. Let's face it, chlorine was used by the military to kill people. It is potentially very dangerous. I've experienced some of its devastating health dangers and want to avoid it. This led me to do research on chlorine. There are many studies which confirm health risks - http://coachsci.sdsu.edu/swimming/chlorine/chlorine.htm Which brings me back to my initial question for this forum - "Are there viable alternatives to chlorine, and if so, what are they?"

The reason for the move away from chlorine is that I was experiencing health issues related to the chlorine. I'm a swimmer and am in an ozonated/chlorinated pool several times a week. Plus, we use our hot tub daily. After a lifetime of absorbing chlorine in my body, I began to have some reactions to the chlorine. Therefore, I've begun to explore options. Are the copper-based approaches effective? Has research demonstrated that they are or not? I'm also curious what readers of this forum have experienced.

Yes, I do have circulation/filtration system that is connected with the ozonator.

Hot Tub Set Up & Water Issues I have a Snorkel cedar hot tub with well water and an ozonator. For years I was using chlorine with Nature 2. When I would first add the water to the tub, it was clear. Then, when I'd add the sanitizer, the water would cloud up to a brownish color. I would then add a product called Metal Free and the water would clear up. For the last year I've been using Clear Water Blue in an attempt to not use Chlorine or Bromine. Clear Water Blue also clouds up the water with a brownish color - except the manufacturer has informed me that I cannot use Metal Free to clear up the water. Clear Water Blue requires daily shocks which bring about wild swings in the PH and alkalinity and need daily attention. And, unless I shock it with chlorine periodically, the water eventually develops a musty smell. I've attempted using an Eco-One Pre-Filter and while it helped some, the problems still persists. The Eco-One vendor suggested I have the water tested and possibly get an iron reduction filter. The water was tested and was found to have a high iron content. A local water treatment vendor recommended a Pentek RFFE20-BB Radial Flow Iron Reduction Cartridge. Questions Any suggestions on the following: A non-chlorine/bromine sanitizer that would work well in the above situation? How to maintain clear, fresh smelling water with well water and a high iron content? Any recommendations on the Pentek RFFE20-BB Radial Flow Iron Reduction Cartridge? Any other suggestions? Thanks.
