EDTA is chelating agent it has heavy metal binding properties and able to detoxify the metal toxicity. Farmers believe that metals contribute to increasing the hardness instead of divalent cations.

Andreas Laggis... Thanks for your valuable response. Here in India Vannamei farmers are believing that the EDTA is reducing water hardness, maybe due to its metal chelating property. According to my knowledge, metal chelating property is found at higher pH environment. Personally I have checked with lab results. Before and after EDTA application there is no change in the hardness of water. But the ...
