Newbie, with a new pool issue encounter

[PoolDoc]

Chlorine tends to precipitate iron, especially when added in large quantities at high-ish pH. Also, industrial bleach (as opposed to laundry bleach) often had quite a bit of iron in it. It's normally chelated by adding sugar during manufacture, which creates gluconic acid, but laundry bleach is filtered to remove the iron.

Your iron could be from one or both factors.

Regarding removal, I have a complete thread in this section on that topic -- read and follow it. It covers the EXACT order in some detail. Take the Metal Free back; it's not chlorine compatible enough to work well for you.

By the way, do NOT stop chlorinating while you worry about the iron -- you don't want to deal with BOTH iron AND algae!. If you want to, you can use polyquat to allow lower chlorine levels, and you'll need some anyhow, during the no-chlorine period of clean up.

Good luck!

Thanks! I had checked the pH regularly and don't believe it was high when the liquid chlorine was added. I have no idea where this product came from, or its quality, and will have to go look at the label and see if I can get more info on what exactly it was. When I glanced at it, I noticed that it was 12.5%, and that is all I noticed.

I'm probably being obtuse, but I haven't found the thread you mentioned about removal, but would be happy to follow it exactly once I locate it. I will also happily return the Metal Free, and Im assuming your thread recommends a more appropriate product.

I have not run the chlorine down to zero as I definitely agree that I dont want to deal with algae too! Thanks for your reply!
