eh... well that’s mr. tangs opinion, but I know also a majority of the paranoid reefers out there think so too. whatever you do, longer or shorter routine, truth is I can guarantee that if they are healthy organisms, and tanks are very well established, they will be just fine.
I simply can't count how many times I've dumped stuff literally within a minute of bringing the specimens to some of my tanks. Always are fine, I cant recall one time that some specimen would have died from improper acclimation or soon from introduction. weather anemones, worms, shrimps, crabs, snails, fish, corals... whatever... marine animals are hardy when introduced into well established systems of good quality and parameters. Taking care of some of them and allowing them to thrive is sometimes yet another story.
