I'm a bit confused between the differences of a QT tank for fish and for Corals/Inverts. So I get the procedure for fish for the most part. But for corals and inverts you wouldn't be able to treat with the copper obviously so is it just a waiting game for the invert tank? Would the invert tank need higher end lighting to keep the corals alive? Also, in both tanks I assume we're throwing away the sponge media after the QT is complete and seeding a new one a few weeks before restarting it correct?
