Well, I've kept it so long waiting to find a use for it that it has begun eating through the plastic containers it was shipped in.

Hi, I have a couple pounds of potassium hydroxide that I need to dispose of safely. I have basic DIY safety equipment and outdoor spaces. How should I proceed?

Correct me if I'm wrong... That means all the folks who think they are drinking water from solar stills that is sans the chlorine and fluoride are mistaken. And, I would be gaining nothing, since my goal is to remove those things so the water in the spa is sans chemicals as well. It would, I guess, remove solids and possibly other contaminants though.

Hmm...the solar still might work. The references I've read say it can get out the chlorine and fluoride. Does that mean those evaporate at a higher temp than water? or do they go to gas rather than liquid? Mac

Hi All, I did some searching in this forum and on the web with little success...really, almost none. Given the drought situation in my area, I would like to avoid refilling my spa because the current water is saturated. This is the term used, by the pool and spa industry, to describe when the chlorine, ph, and hardness chemicals have been used for a while and basically don't do much anymore. I've looked at reverse osmosis filters, but it appears they dump a high percentage of the water forced through them. So, is there a way to chemically cause the precipitate out or a different way to remove the chemicals. I'm chemist and don't play one on tv...I do have a pretty good background in engineering, so I'm not afraid to tinker... Any ideas?? Regards, Mac
