Now there are certain cleaning methods that allow the pond to still have water in it. We like to drain the pond instead so we can do a more detailed clean.
There are some worries that this method can hurt your pond’s ecosystem, specifically the beneficial bacteria. Don’t worry, if done correctly the draining will not have any lasting negative impact on your koi pond.
Here is how to drain your koi pond:
If you have fish, use the sump pump to drain 1’ of water
Put some of the pond water into the tub for the fish (it puts less stress on them)
Now move your fish to the tub
Finally, drain the rest of the water out
But don’t start cleaning it just yet.
2. Check Your Koi Pond For Problems
Sometimes small problems can become more recognizable when the water is gone. That makes this is an excellent chance to look for any problems with your pond:
It’s better to fix these issues now rather than let them become major complications later.
3. Clean The Pond Shelves And Walls
Plant matter and muck, in general, can worm its way between the rocks. It gunks up your pond and makes it look…messy.
You can flush that muck out using the sump pump and your pond water. It’s both convenient and environmentally friendly.
Now you just have to use the vacuum pump to remove the waste.
4. Power Wash Your Koi Pond
Scale, algae, and debris are still left clinging to your pond. Left alone it can build up and hurt your pond’s look and ecosystem.
But you have a pressure washer.
Holding it too close to the rocks can damage them, the beneficial bacteria, and the liner, so take care! 8” or more is enough room to clean the rocks with damaging anything.
The pond part of the pond is now clean, but the rest isn’t.
Step 6: Cleaning The Biofalls & Putting It Together
Your waterfall which makes the most relaxing sound needs cleaning too.
That’s because it also serves as a filter for your pond’s water. The biofalls (biological filter waterfalls) is made of 3 parts appearing in this order:
Take each part out and clean with the hose and/or sump pump. Then you’ll want to put it back together in reverse of the above order.
Now your biofalls should be beautiful and working smoothly.
Step 7: Cleaning The Skimmer Parts
Leaves, plant matter, and debris are all caught by the skimmer (mechanical filter).
This one needs cleaning every so often because it catches larger debris. The filter mats also need cleaning.
You’ll notice something different though: a pump is attached to the bottom of the basket.
Unattach the pump
Take out the skimmer
Clean the parts as you did with the biofalls
Put it back together and now you have a clean skimmer.
8. Refill Your Pond And Put In Your Koi Fish
Don’t put the fish in yet!
Putting fish in new water right away can be harmful. It’s chock full of chlorine, fluorine, and other types of -ines. Thankfully, you can prepare the water for your fish with a pond detoxifier. Neutralize those harmful chemicals and get your fish back home!
You’ll want to follow the correct process for introducing your fish. They can get hurt if you don’t and nobody wants that.
9. Enjoy Your Amazingly Beautiful Pond
You deserve to feel proud of your pond. It should have clear water, beautiful plants, and happy fish.
Now it does.
Bonus Step: Netting For Fall Maintenance
Your pond has a new enemy during fall: leaves.
They can easily clog filters and obscure the water. Left alone they can break down and become the muck laying on the bottom of your koi pond.
The best course of action is to stop them from getting into your pond using netting!
A Clean Koi Pond Is A Happy Koi Pond
And happy koi ponds have happy owners. You too can be the happy owner of an amazing pond! The good news is, you don’t have to do it yourself if you don’t want to.
