I have looked through the forum and I can't find a reccomended TFP method to treat metals, just a bunch of discussions.
My pool store has the following two products:
Metal Free by Natural Chemistry
Metal Klear by SeaKlear (now owned by Natural chemistry)
I also found this product that claims to remove the metals:
The Copper test kit is not that expensive, but the Iron test kit is a bit expensive. The Pool store by me has strips that show both. Should I find a pool store that has the better test kit?
