This might sound like a crazy question. I know copper and inverts don't mix. But could this be used on your motile inverts instead of putting them in a fallow QT for 76 days? Additionally, could this work on removing fish parasites (and other issues) from coral you have in QT?
I don't think that would work. I forget the different names, but fish have the parasite in the feeding stage (falls off 3-5 days) while inverts would have them attached in the dormant/breeding stage (up to 28 days). The point of TTM is to rid fish of the parasites that fall off while not giving any new ones time to attach.
