I've been a silent follower of you all for years - my pool thanks you.

I' curious about the best all-around metal remover. I truck in water each spring because I have well water that’s not great. I do use the well water to cover evaporation, etc., and after 12 years, I now have sufficient metals in the water so that when I shock, I occasionally get temporary metal staining.

What is the best way to remove the metal, and is there one type of remover that covers all/most metals so that I don’t have to try to diagnose what type is most prominent?

Thanks,
Jeff
