Acros & wieners, oh my!
Did you find the source before you tried to remove the W? I was all set to just to a series of water changes and was told that, if I have removed the source, the tungsten should slowly just reduce over time. I think that Ehsan had numbers as high as 500 and just let them come down naturally and all went well.
Yes, they specifically wanted to test if the Tungsten would be removed with no water changes. Algal export and bacterial sequestration appeared to work to effectively reduce the value in their tank. I think with several of us having rusty pump issues it is clear that we all should regularly check all mechanical components for this kind of degradation on a regular basis.
