Use a fine mesh net to collect the debris from the water. If a rotten odor is given off by the pond when the debris at the bottom is stirred, stop and see step 6. Otherwise, use the net to remove debris at the bottom of the pond.

Drain about 10 to 25 percent of the water while continuing to remove the debris.

Refill the pond's water. Use either a homemade or store-purchased dechlorinator to remove chlorine from the water that will be placed in the pond.

4
Add the water slowly so that the koi in the pond are able to adjust to the water's temperature. Pumps and air stones can oxygenate the water that is being added.

5
Remove the koi from the pond if you smell a rotten egg type of smell when disturbing the debris at the bottom of the pond.

Use a small pool, such as a toddler's wading pool, to hold the koi. Make sure that pool does not have any chlorine residue and that a dechlorinator has been used on the water in the wading pool.

Drain the pond completely. Clean out the debris and proceed to steps steps 2 through 5. You need to refill the pond on the same day so that the koi can be returned.

8
Place the koi into a large bowl of dechlorinated water in the pond. Place this bowl into the pool so the koi are able to adjust to the water's temperature slowly. Keep an air stone with them.

9
Place the koi into the pool with a pump or air stone after about 20 minutes in the bowl.

Tips & Warnings
Besides the koi, other animals live in the pond. Remove any animals such as snails or larvae from the net. These animals promote pond health and should be returned to the pond.
Skim the water about 10 minutes after feeding to remove any debris before it settles to the bottom of the pond.
There are filters and drains available so that draining a koi pond is no longer necessary.
Test the water on a regular basis.
