The majority of the acclimation guide is intended for introducing animals recently purchased online into a quarantine environment that have been inside a dark box for 24+ hours and the water quality is most likely degraded from waste. Hopefully you followed these steps before introducing your pond animals into their quarantine environment. After the quarantine period the acclimation from this environment should be relatively easy and quick – given the water parameters in the quarantine environment are ideal and similar to your pond. The best way to move the fish would be to put them in a 5 gal. bucket and float the bucket in the pond for at least 30 minutes so the temperature in the bucket can gradually reach the same temperature as the pond. Make sure you do this in a shady spot of the pond or during a time period when the bucket will not be in the sun. In order to keep the bucket from tipping it may take some creativity but it may be as simple as using a wooden pole laid across the pond centered through the bucket handle to achieve this. Make sure to add a small air-stone to the bucket to agitate the surface so the oxygen and pH levels don’t change. From there you can gradually introduce pond water to the bucket and remove the mixed water until you are confident that the majority of the water left in the bucket is water from your pond (should take no more than 20-30 minutes). From there, gently scoop the fish out and place them in the pond and discard the water from the bucket.
