marine salts

As far as the heavy metals goes, I wonder if using a water conditioner in your tank that binds heavy metals so they can be removed with carbon

I asked several people about that and no-one seems to know for sure.

From a rather long discussion between Dr. Ron and Randy Holmes-Farley I gather that heavy metals are not particularly soluble at high pH, and bind rather quickly to a number of organics renering it less bio-available.

I wish I had the $ to run some additional tests.

It would be interestint to take some samples from one bag of salt and run half of them through carbon for a while and then test for heavy metals to see if there is a significant reduction.
