Green Pool during Stain Treatment

[mbar]

You don't need anymore polyquat. Your water may have turned green when you had high ph and added high chlorine. The sequesterant probably kept the metals from falling out onto the surface of the pool. Just a chemical reaction - hopefully you don't have algae, but if you do the chlorine will kill it. The chlorine can also just be getting used up getting rid of the vitamin C. How does the water look today?

It turned from green to crystal clear in about 8 hours! I dropped the pH and I think that made the difference. I also added some more metal out and am adding lots of bleach to bring the CL level up. Looks great now! Thanks for your help.
