Just so you know, the above posts are accurate. Trans-shippers and wholesalers have now begun sending printed instructions to lfs that say - float to equalize temp, cut open bags, dump water, insert coral into display / sale tank. More important to "light acclimate" new arrivals. My friend owns a lfs and has showed me the new acclimatization proceedures he is recieving. He has also been getting snails and hermits with only wet paper in the bags and has had a much lessened loss rate!
