I would probably mix up a test batch of SW and measure out exactly 1 gallon then add Copper safe as directed using a syringe. Then test the water to check your Hanna Tester for accuracy.

Me... the way I roll... (

), based on all that you've said, and what I see after 21 days, I'd get the Copper back to where you had it at 2.5-2.7 and go enjoy your short vacation. Best wishes for great success with your beautiful fish.

Not a bad idea. I just checked the now empty QT tank and it’s still showing 2.25 despite it being empty for a few days now.

Not a bad idea to calibrate the Hanna.

Unfortunately I added him to the DT after 28 days. So no going back into QT at this point unless I bring the whole display. All those spots popped up after a few days in the DT without any medication.
