Normal Chlorine Usage?

[Labpool]

Thanks, that was the answer I was looking for. Just wondering if there are ways to reduce chlorine levels and still stay away from algae. I understand the BG chart and basic pool chemistry. What I don't understand is how some people are able to run FC at like 1-2 ppm in their pools. A friend says he used the Frog Mineral System? in his pool. It seems like a gimic to me with the softer water and minerals, though it would be nice to use less chlorine. My skin gets crazy dry just sticking my hand in to test the water. And after swimming I can feel a difference on my skin. It just feels drier.

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.
