So experiment #1 failed. 48 hour quarantine soak with 24 hour clean water soak failed. 3 days after being back in DT the BCP are opening back up.
So, this time I think I will try to remove all my inverts and corals that I think will die when I treat the DT directly.
The only things I removed from my tank were snails and large brittle stars. I don't even think it was necessary for the brittle stars because I seem to have some large ones in my refugium I was unaware of and found after the treatment that made it through without any issues. Only the corals I expected to be affected were. All the BCP, GSP and Xenia died. (I removed all the GSP and Xenia I could, what was left behind died). Other than that I did not lose any coral , fish, inverts as a result of treatment.
