Here's a good post about the pool frog by pooldoc: http://www.poolforum.com/pf2/showthr...9669#post69669 Here's a much more detailed writeup on the subject: http://www.poolforum.com/pf2/showthr...-amp-More-quot
Personally, I wouldn't want to swim in a poolfrog pool due to the lack of sanitizers killing viruses and bacteria.

You can successfully run very low chlorine levels like that if you have no CYA; you're just going to have to add chlorine many times a day to keep the level at 1-2ppm if it's an outdoor pool exposed to UV from the sun.

If you just want to be adding chems less frequently you could raise the cya level as aylad suggested, or perhaps look into a swcg to generate chlorine for you.
