Very High Chlorine, Advice Please?

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!

Deb, welcome to the forum! You seem to be starting to understand why so many people come here, the info here is stuff you're not going to get from your contractor or pool store -(IMHO, it's not so much that they want to sell you BS chems, they are just ignorant of what's really happening, chemistry wise and since they make money off of it, they have no incentive to change what they are doing [that is to say, they aren't doing it out of malice]). You have made the best decision in comming here and learning how to take care of your pool without having to rely on the 'pros'.
If you rid yourself of the Nature 2, and can afford it you might want to look into a salt system, there is an area here which deals exclusivly with those systems, you could do a little reading and decide which one would be best for you. You've already received excellent advice as per your chlorine ? , but if you have any more ?s, just post and someone here will help you. Again, stick with the 'not for profit' advice you get here and give the forum and poolsolutions a good read - it'll clarify things for you greatly!

Deb,
I don't know what those shocking products are. But they are almost certainly Di-chlor, Tri-chlor, or Cal-hypo.
All basically add chlorine to your pool but also add other stuff:
Di-chlor and Tri-Chlor are VERY acidic and lower pH--even if you don't want them to. They also both add stabilizer (CYA or Cyanuric Acid) even if you have enough and don't want more.
Cal-Hypo adds calcium to your water at the same time.

Ordinary laundry bleach is Sodium Hypochlorite--the same stuff as "Liquid Chlorine" or "Liquid Shock" at your pool store. Bleach has NO side effects--it adds NOTHING but chlorine. You need 4 gallons of regular bleach to reach 15ppm. Or, if you use Ultra bleach, you need 3 and 1/2 gallons. You can pour the bleach in the return stream or the skimmer (while the pump is running).


As for CC, there isn't really a magic number, but a lot of us have noticed that we cannot get 0 CC and instead finding that our test indicates less than .5ppm of CC and that seems to be harmless. But if it's CLEARLY .5 or above (and you have .7) then it shock time.
