metal sequesterant. What to use?

[waterbear]

Just about every sequesterant on the market is based on the same group of chemicals (dreivatives of phosphonic acid) I know of one that is based on the chelating agent EDTA, MetalFree by NaturalChemisty. I have used that one along with several others and they all seem to work. Can't really tell you which one is best but I have had good luck with the MetalFree, Proteam's Metal Magic, and the Jack's Magic line (the Pink Stuff for iron). Just make sure to follow the directions for dosing, pH,and water balance instruction before you use one for it to work properly. Adjusting your pH to the proper levels recommend on the label first is a most important step!
