Paraguard use in DT?

[Reefie]

So.........I'm in a losing battle with an extreme case of Ich. I've got a QT set up now, but there are a few remaining fish in my DT that I just cannot catch.

Is it safe to use Paraguard in the DT? I've got mostly SPS with a bit of LPS, and 5 Crocea Clams. Paraguard isn't Copper based, but Seachem won't call it reef safe.

I'm not too worried about the CUC, but it's the clams and the anemone that I'm treasuring. Has anyone tried dosing Paraguard into their DT?
