No problem, I love it when people go looking for an answer and show that they are willing to learn, heck I'm still learing.
How do I acclimate my new anemone?
Acclimation procedures for anemones are similar to acclimation procedures for other sensitive invertebrates. When you first bring an anemone home, you will want to float the anemone bag in your reef tank in order to equalize temperature. After 15 minutes or so, you will want to open the bag and start to slowly dilute the bag’s water with water from your system. There are many ways to do this, the easiest of which is referred to as “drip acclimating”. Drip acclimation consists of setting up a small line of tubing that has a very tiny amount reef water running through it from your system’s pump, and allowing a small amount to “drip” into the anemone bag, so that over the course of an hour or so, the water in the anemone bag is completely replaced with water from your system. When you remove the anemone from the bag, gently place it somewhere in the tank where the environment is best suited for the anemone species. Be cautious about providing too much light too soon for an anemone that may have been out of bright light for a while.
Yeah I like to see about a 2 hour drip acclimation for an anemone that is shipped with very little water. But it doesn't stop there. During the next couple weeks your anemone will be expanding and contracting, maybe even moving as it gets used to your water paramiters.
As to the air question, well I would guess your right, hadn't thought about it.
