If you're talking about quarantining corals, it all depends on your setup. If you have a QT with lighting that will support them, then it's probably a good idea. But most folks I know of, don't. I don't. I figure the risk of bringing in pathogens/parasites with what little water is transferred is minimal. If you're doing a proper drip acclimation, that LFS
water is pretty darn diluted by the end anyway. And a good shaking to get off any excess gets rid of even more.
