Acclimatization

Share

Acclimatization is the method, through which, a organism will adjust to a change in its environment. The water on which the fish were packed is at a temperature, pH and salinity than the water in the aquarium. Fishes, and specially invertebrates, are very sensible to subtle changes in these parameters. Due to this fact, an adequate acclimatization is required, to prevent stressing the animals.

Here present are two recommended methods.

Drip Method:

-Turn off the aquarium lights.

-Dim the lights in the division where the package is to be open for the first time. A sudden exposure to intense light can cause stress.

-Leave the closed bag floating in the aquarium for 15 minutes, allowing the temperature in the bag to adjust, slowly, to the aquarium water temperature.

-Carefully empty the bags content (including the water) in a recipient, guarantying that the animal is completely submerged at all times, and that there is enough space for more water.

-Using a small hose, syphon, slowly, water from the aquarium to the recipient. To ensure a good acclimatization, only add small quantities of water.

-When the water volume inside the recipient doubles with the new water introduction, discard half of the recipient’s water. Restart syphoning water from the main aquarium until the water volume double again.

-At this point, the animals can be transferred to the aquarium. Sponges, clams and gorgonians shouldn’t be exposed to air, so transfer them in a bag or small recipient. A net can be used for fishes. Avoid touching the soft parts of corals.

Float Method

-Turn Off the aquarium lights.

-Dim the lights in the division where the package is to be open for the first time. A sudden exposure to intense light can cause stress.

- Leave the closed bag floating in the aquarium for 15 minutes, allowing the temperature in the bag to adjust, slowly, to the aquarium water temperature.

-Add a small amount of water from the aquarium to the bag.

-Repeat step 4, in intervals of 5 minutes, until it is no longer possible for the bag to float. As soon as the bag loses its floatability, discard half of the bags water.

-Reposition the bag floating in the aquarium; add a small amount of aquarium water, in intervals of 5 minutes, until the bag reaches its capacity.

-Remove the animal from the bag and carefully place it in the aquarium.
