nem acclimation

Received a new bubble tip anemone from Cultivated Reef via fedex today... (LATE, like 5 pm) Would it be a problem to leave it overnight in the shipping container? Hoping that I can place it tomorrow with lights on to prevent it from moving around too much overnight unsupervised.

Acclimation time! How long to you let the BTA’s drip? Salinity is still pretty high for my tank… my tank is about 31.9 and water with nems are 34.4 ppm. They have been in there for about 2 hours and 15 minutes.(I just took some water out of the bucket they are in) Also what is this white stuff...
