This looks bad

[Jay Hemdal]

Out of curiosity could I run a qt for 30 days running copper and at the same time in the display run hyposalinity to skip a 78 day fallow period?

Can I also run hyposalinity on the qt for an added redundancy?

The fallow period for ich is 60 days. Any invertebrates need to be held in a fishless system for that long.

Both copper and hyposalinity speed that up and can be concluded in 30 days, but I usually go with 30 days AFTER the last ich spots were seen, just to be safe.
