QT a CUC?/ how do you bring in new livestock

[Animal-Chin]

Another tip, test the water in the bag before you put the fish in QT or your tank. I run my salinity at 1.025 and my alk at 9-10.

I've brought home fish and the water was 1.015 with alk of 5. This is a huge difference and unless you slowly raise the levels your fish is going to really feel it. inverts may just die and fish will be stressed. Drip long and slow to ease the transition to your reef levels.
