Tony, might be easiest to yank the substrate. I've had to do that with Eco, as I said before. And my guess (total hearsay, BTW) is that I read somewhere that Caribsea use to keep their substrate outside in a yard. And they make a lot of reef substrates. They are in Florida. Hurricanes might equal contamination. That said, Caribsea has been good about replacing "corrupted" substrate. There is a long thread, actually a couple on this same topic, should you care to search.
