greenish pool water from my well

Hi, I wrote before about my green pool water, I have found out it is from the metal from my well. It was suggested to me to get something called metal out. I purchased something else called hth metal and stain defense. Will this work too? I thought it would because it says it prevents metal stains and scaling, aids in removing fresh metal stains..tho I have no staining, and it also prevents mineral deposits on equipment. I am really hoping this works. All the tests I did came out great. I just put more chlorox in for overnight, and the pump is running. Wanted someone's opinion before I put this in my pool tomorrow. Thanks, I hope someone can answer me!
