What do mean trick? There is no standard. Some people do like 12 hour acclimation, some just open the bag and drop in (drop and plop method). I think I remember reading that if they are coming from a very high TDS/GH water into a lower one, they can take that faster and easier than going from a low TDS/GH water into a higher one, but I can't remember where I read that or if it's true.
It's the opposite of that, because of osmotic pressure.
