The proper acclimation of a new arrival is extremely important considering the amount of stress the coral has endured before arriving at your door. We recommend that the following procedure be followed immediately upon receipt of the livestock. The entire process is actually very simple and should take an hour to complete.
Step 1: Turn the Aquarium Lights OFF
The livestock has been in complete darkness for the last day, and will not immediately adjust to high output aquarium lighting. By turning off the lights, you remove a possible source of stress for the new arrival.
Step 2: Float the Bag for 10 Minutes
First remove the outer bags and float the closed inner bag for 10 minutes. There is a good chance that the bag's temperature is significantly lower than the temperature of the tank. The initial floating period allows the temperature of the bag and the tank to equalize.
Step 3: Add 1/2 cup of Aquarium Water
Open the bag and pour 1/2 cup of the aquarium's water in. The slower you add the water the better. Corals and other invertebrates are sensitive to fluctuations in pH and especially salinity. If possible, drip the water in the bag. Repeat this step every 5-10 minutes. If the bag fills completely, empty half of the bag's contents into a drain. We do not recommend pouring the mixed water into the aquarium since it likely contains all sorts of mucus from the stressed coral that may be toxic.
Step 4: Release the specimen into the tank
Find a suitable location where it will receive the appropriate flow and lower light. It will need a few days to adjust to the new lighting.
If you have access to a quarantine system, we recommend using the above method to first acclimate the new arrival. After the quarantine period is over, repeat the procedure to introduce the specimen into the display tank.
Using an airstone to oxygenate the water in the bag during acclimation is not recommended. The pH of the water may rise quickly and cause damage to the new arrivals.
