QT tank

[jetstream37]

I've set up a QT tank a couple of weeks ago for any new fish to go into my display tank. Now my question is should I be running this tank 24/7 along with the display tank. I've been cycling the QT tank with water from the main tank. Should I do fresh salt water changes weekly too? Along with testing? What treatments should I be giving new fish in the QT IF any or should I just observe the fish for 4 to 6 weeks and treat as necessary? Should the light be on at all in the QT? Or just when fish in there. Should I put new corals in here too and do coral dips separately

I would always start with fresh water and use Bio-spira and marine pure blocks to start a new QT. I did use copper though, but didn't have issues.

I QTed a ton of fish btw

Always got them eating, even the picker straight from the diver ones.
