Tangs for dummies

[Humblefish]

Same as your display if you are transferring fish from the display for treatment. If receiving new fish, then you want it the same as the water in the bag the fish is arriving in. The only time I have ever adjusted the salinity is if the salinity of the water in the receiving bag is lower than mine.... so I will raise the salinity to match my display's salinity.

+1 Typically the SG new fish arrive in will be lower than what most of us keep our DT at (1.026). So, you'll want to top-off with SW until DT matching salinity is achieved. Set QT temp to match the DT, and then you can just net & release once QT period has ended. Just another reason to QT.
