“For what? It isn’t Christmas,” laughs Brian.

Amy smiles back at him. “‘Tis pond season! It’s time for us to wake up our koi pond and get it ready for spring.” Brian nods. “Aha, it’s that season. What do we need to do?”

“I… don’t know. It’s our first spring with a pond. What’s the spring koi pond maintenance process? I remember seeing something about it when we were looking up winter pond maintenance…” says Amy.

Brian unlocks his phone. “Let’s look it up on Google. I’m sure we can find out what it is before we get one of the local pond contractors to clean it.” He starts searching Google as Amy comes to look on with him.

Here’s what the couple discovers:

  3. Unplug the waterfall pump

  16. Pull the pump and fill the pond
  17. Use a pond detoxifier to clean the water for the fish
  18. Reintroduce the fish
  19. Watch your pond re-establish its ecosystem

What To Know About These Steps

Putting the tub in the shade keeps your fish cool. Tubs can heat up when in direct sunlight for a few hours. The net keeps them from jumping out.

Keeping some water in the bottom makes cleaning the debris easier.


Keep the pressure washer about 6 to 8 inches above the rocks. Leaving some of the algae and muck on the rocks is good for the pond. Nature included it in a pond ecosystem for a reason.

Pond detoxifiers neutralize chlorine, chloramines, and heavy metals from the water. This makes it healthier for your fish. It also makes introducing them to the new water easier.

To introduce your koi fish to the new water, put them in a bag filled with the old pond water. Set it in the shallow part of the new water. Let them sit for 20 minutes. Then, start splashing water into the bag. After doing this for a few minutes, let them out.

Putting fish in new water right away can be bad for them. It can send them into shock.
