So I've been horrible about QTing new livestock for my tank. Everytime I have set one up it's been somewhat last minute and I lose most if not all of the QTed inverts. When I drip, dip, and add them to the DT I have minimal losses. I hate doing that because 1 bad purchase can ruin the whole tank. Do you typically keep a QT set up and running? If so, do you drain and disinfect after transferring livestock to the DT?
