Iron staining product recommendation?

[Antneye]

I was told to get metal out for my pool by my pool company because I have a lot of iron and staining is starting to occur. I have researched the threads talking about the whole iron process, but when I go to purchase metal out I see multiple different brands. Can someone let me know which is best?

From Sequestrant - Further Reading

Sequestrants based on HEDP, phosphonic acid, or phosphonic acid derivatives are the most effective.

The top sequestrants are:

• ProTeam's Metal Magic
• Jack's Magic The Pink Stuff (regular)
• The Blue Stuff (fresh plaster)
• The Purple Stuff (salt)

You can also find many other brands with similar active ingredients, some of which are noticeably less expensive.
