ok but how will you decontaminate your sump from copper after that? this is very dangerous if it is connected to your main tank as any trace of copper might kill all your corals, and only a tiny amount will do that.
I speak from experience having lost a lot of corals from copper poisoning from carbon. There was not that much of it in my tank, yet I lost a lot of good pieces.

Effectively, turning that one valve isolates 3/4 of my sump from the tank above it. Normally I use that valve do do water changes right in the sump, as the largest chamber in the sump is about 50 gallons, but for the hypo process I had the fish in there.
It was an experiment to see if it would work at all, and in my case it didn't. It was too tricky to keep the salinity maintained perfectly because the ATO system was plumbed in to the return chamber, so I had to add water to the QT system by hand. Also, I'm pretty sure there was some splash back from the DT.
I'm sure there are cases where hypo can work, but I didn't have the right set-up for it. Cupramine is pretty much guaranteed to work, and is way more forgiving on my end, though I recognize it's harder on the fish.
