That's what I want to know. I will have my water analysed by a pro lab Thursday. I had done this analyse for heavy metal and all metal about a month ago, so I will be able to compare. We will also run carbon in a bucket and anayle that water, just to see how much of the metal could have leached.
My greatest concern is if the liverock have absorbed these heavy metal. I will now use polyfilter for a few months until my system return to total normality.
You don't have to flush the tank. I will post here my result on my tank as how far this contaminant went and how much of it still remain.

Another thing I'm worried about now is, once you put bad carbon into your tank, how easy would it be to get all that nasty stuff out??? It's almost like you have to flush the tank just to be sure.  |
