Some people will run their QT as a copper system. I encourage just UV
. Keep a piece of rock in your sump you can easily toss into your 29g to make it a QT tank for 2weeks with a 1000 GPH
or higher pump. Toss in a bunch of PVC
pipes of all different sizes everywhere and have a tupperware full of sand you can easily remove.
Take this time to really make sure the fish is eating. Offer it every type of food until it's eating. Obviously keep it clean. bare bottom is preferred. Carbon/Purigen are nice together if you had a spare HOB
Was this a tank that you planned on running 24/7 or just when you buy new fish/coral?
