Small ponds can be drained and filled in about a day. Larger ponds will take two or three days for professional removal.

When deep cleaning your koi pond, transfer fish to a clean, uncontaminated container at least one foot deep, like a large bucket, tub, or kiddie pond. Fill the container with their existing pond water to avoid shocking them, and place the container in full or partial shade. When it’s time to reintroduce them into the pond, slowly add the new water to the container before adding the fish and container water back into the pond.

Deep clean your koi pond at least once a year to keep your fish healthy and your pond in good shape. Water testing, debris removal, and partial water changes should be performed weekly. Seasonal professional service will ensure everything is clean and functioning properly.

You have several options for your pond by getting your yard ready for the winter. You can winterize your koi pond by ensuring it’s at least 5 feet deep so it doesn’t freeze completely, installing a pond heater or aerator and having it run at all times, and installing a deicer if temperatures are dangerously low for an extended period. You can also choose to shut down your pond for the winter by removing all the wildlife in it and bringing it indoors, cleaning out the filter and pump, and then covering the pond with a tarp.
