How do I keep my pool water clean without nasty chemicals?
Is there a chemical-free way to keep pool water safe and healthy, that is without chlorine or bromine?
How about using UV radiation to sterilize the water?
Still chlorinated, but if handling chemicals is the issue, how about a salt water pool?
The alternative I've seen pushed is copper-oxygen system. I can't say how effective it is, but last I checked it is not approved by the EPA for sanitizing water. I've also read that they take more attention and care.
Just based on experience having a pool in full sunlight - UV isn't going to do the job by itself. I think the filters they sell are designed to reduce your chemical dependency, but not eliminate it. Same with ozone generators.
Salt pool and baquasil are your two best options. (although technically salt is chlorine)
Remember, you're trying to kill all living things in the pool. "no chemicals" and "no living things" tend to be mutually exclusive.
Ozone treatment is another option. I have swum in two ozone pools - the two obvious benefits:
- very clear water. Unlike chlorine or bromine, which both make the water cloudy, ozone treatment leaves the water incredibly clear
- no stinging eyes. This makes a huge difference to me, as my eyes react quite badly to chlorine.
