Ok. I admit I do not have a QT
even though I know I should. However, I do not often add that much stuff to my tank and it seem like a pain to keep a tank going just for that occasion. Is it possible, a day or so before new live stock arrives, to syphon off water from the main tank into a smaller tank and put a couple of pieces of LR
from the main tank into the QT
without going through a cycle. Then if all goes well with the quarantine period then you can break the tank back down and add back to the display. Of course if all does not go well you would probably be out a couple pieces of LR
...but better that than your whole display tank being infected.
