Yep, #1 is your best bet to rid the parasite. You may see faster results from FW dips, but sometimes the parasite returns back into the system. Quarantining is always the safest and most reassuring procedure because you wait it out and starve the bug off.. Not just on your Hippo Tang, but also in the entire ecosystem..:

Note: Paragraph 5, Treating Cryptocaryon:.. Read this section of the article very closely.. "..Since copper is extremely toxic to invertebrates, treating Cryptocaryon in a reef tank poses special problems.."

Go with option #1 and treat the tang using hyposalinity treatment or copper. They are the methods that will work every time. With either method, leave all LR or other calcium sources out of the tank. Here's a good website to check out. ATJ's Marine Aquarium Site - Reference - Hyposalinity Treatment

You can use live rock. Or soak the bio wheel in your sump for a few days.

I if you use copper the rock will be fried.
