“Whelp,” says Adam, “there’s no going back now. Let’s focus on what we can do to fix the problem. We need to know how to clean a koi pond and how to keep a koi pond clean.”

“Great idea! They do have a blog that’s helped us before, like with how much it costs to build and maintain a koi pond,” says Adam. He gets his phone out and starts looking.

More Details On These Steps

Inspecting the pond means looking it over to make sure it works. We’ll turn your feature on to make sure it works smoothly and doesn’t leak. We’ll use a solution on the pump to make sure it keeps working.

Draining the pond helps us really get it clean. We won’t clean it 100% because that’s not what nature intended. Ponds need some muck and algae, it’s part of the ecosystem!

Taking out the fish gets them out of the way. We put them in a large container we fill with their pond water. We also put an aerator in it. This makes sure they’re comfortable.

Cleaning out the debris involves removing sticks, leaves, and other gunk.

Flush, powerwash, flush loosens the hard-to-reach and caked-on stuff. We flush all of that mess out too.

Checking the lights makes sure they all work and don’t have damage. We can also add in lights and other additions at this point (like an Ion-Gen water purifier).

Trimming the plants keeps them looking good and staying healthy.

Refilling the pond happens with a garden hose.

Treating the water gets the chemical balance in line with what your fish need. They’ll feel more at home and are less likely to go into shock being in new water.

Returning the fish slowly helps make sure they don’t go into shock with the newer water.

How To Keep A Koi Pond Clean

The best way to keep a koi pond clean is seasonal maintenance. Spring, fall, and winter pond maintenance keep your pond running smoothly and looking great. It’s all part of how often people clean their ponds.

We hired Just Add Water to create a waterfall feature in our backyard. What we didn’t expect was the overwhelming beauty that happened when they were finished! Chris came to our house on a Sunday, no less, to plan our design, and his crew worked on a Saturday after a long week to do our project.

Amazing, stunning, and much more than we ever dreamed! Professional, and over-the-top design, you won’t be disappointed!!
