First I would like to know what kind of lighting and what kind of sps you have. Then I would say whether or not acclimating is needed. It is not a water acclimation, although I would still float but that's me, it is a light acclimation. You need to know if it is wild or aquacultured and what kind of lighting it is used to and then use that info to determine what kind of screening you should use.
