How do I know that the QT tank is safe?
By safe, do you mean ready to support a bioload of fish?? Or do you mean no disease, or parasites??
Ready for fish... Testing throughout the cycle will tell you if a tank is safe for fish.
But you really can't tell if your QT is safe from disease or parasites (other then the fact that it is newly setup system that never housed any animal ) until you put a fish in the QT. The QT tank will not give the fish a disease or parasite, but rather the new fish will introduce a disease or parasite to the QT tank.
The reason you would want to add your first fish to a QT is that if it ends up having some sort of issue, it is already in a tank that can easily receive treatment (you don't need to catch the fish from the DT).
