Thanks so much everyone. I'm very appreciative and overwhelmed by so many helpful responses. I will definately look into the nature 2 very closely, maybe I can even return it, they shouldn't sell a product that results in metal getting into your pool, thats insane.

I shocked the pool (with Burn Out Extreme) June 2nd, its ok to shock it again so soon? What is the magic number of CC that suggests shocking is needed? Its so funny you are all telling me to shock. My pool directions are to shock with Shock and Swim once a week and Burn Out Extreme once a month and today the pool guy told me to skip the Shock and Swim this week cause it will only add more chlorine to the pool! I guess I have alot to learn. Glad I found this forum.

If I get rid of the nature 2 is there any piece of equipment I need to add?

Oh and my pool is 27,000 gallons. And interestingly enough I am also adding an alegicide to the pool even with the nature 2.

Thanks again, I know you will all be hearing from again real soon!
