pool care with the nature 2?

[donaldm823]

My friend has a nature 2 and she said it works.
Will my blonde hair turn green if I use it? Do you really need less chlorine?
any information will help me. she said she uses powdered shock with it. I would think both kinds are the same.

My new pool came with Nature 2, and I removed it halfway through the pool's second season (Aug 07)(vessel leak). I found that running at the low chlorine levels needed to save money per the Nature 2 recommendations (they recommend 0.5ppm), your chlorine free inventory is so low that it may not battle an immediate chlorine demand (like a big rain storm, lawn work, pollen or kids). After battling some algae cloudiness in July with several chlorine shocks, I raised my chlorine to a 2-3ppm range and all my problems went away for good. I ended up removing the Nature 2 the following month due to a vessel leak and I saw no change in pool quality (of course my chlorine level was now at 2ppm). As for green hair-I never had a problem with the issue and my wife has blond hair and swims daily-I believe the Nature 2 copper levels are too low to cause that issue.
