Eric,
I asked this in a pm but for the benefit of others here I'll post it again:
In using all the fresh clams, mussels, oysters etc., do you at all feel you are adding a substantial amount of metals into the tank?
I read somewhere out there about the high levels of certain metals in the clams, oysters & mussels you use in your recipe and was wondering if any testing was ever done on any of the molluscs included in the recipe?
I'll find the research on the topic of metals in these kinds of animals and post it if you feel it's at all relevant.
Thanks bud.
