A clean fish pond is essential for the health and well-being of your fish and plants. 

To maintain a healthy and clean fish pond, it is recommended to clean it every one to three years. The frequency of cleaning depends on the amount of debris that enters the pond. If you regularly remove debris and maintain good water quality, you may only need to clean your pond once every three years. However, if you allow more debris to accumulate, it may be necessary to clean your pond annually.

While regular skimmer emptying and sludge removal can help keep the pond clean, a thorough clean-out is still necessary every few years. With proper filtration and a balanced fish population, a clean-out every three years may suffice. However, it's important to monitor the pond regularly and adjust the cleaning schedule as needed.

We recommended that fish pond owners clean their ponds at least once a year to maintain a healthy environment for their aquatic pets.

When it comes to cleaning your fish pond, timing is everything and for optimal results, it is recommended to clean your fish pond in the early spring season.This is because its important to wait until the beneficial bacteria colonies have fully awakened from their winter dormancy before attempting to clean the pond. If you clean it too early, you risk wiping out these helpful microorganisms, which can cause the water to turn green as the bacteria try to re-establish themselves and may lead to a build of toxic ammonia and nitrite which can be life threatening to your fish  To avoid this, it's best to wait until late spring or summer to clean your pond. By taking the time to clean your pond early on, you can ensure that it stays healthy and beautiful throughout the year.

Follow these simple steps to get your pond looking its best and your aquatic life thriving.

Remove the fish and Plants 

To clean your fish pond, you'll to remove 50-70% of the water.  This makes it easier to catch the fish and remove the plants. You can use a pump and discharge hose to transfer roughly 50 to 70 percent of the water into a temporary tank that will house the fish. Your existing pump will do nicely for this, just attach a hose to to pump the water into the temporary tank. make sure that you setup this temporary tank for the fish in a shaded area and if possible use an air pump to aerate the water while the fish are in it. Don't worry if this water is a bit murky the fish will be fine. Ensure that your plants are also kept wet as they can dry out extremely quickly and this can severely damage the foliage.


Drain and scrub the pond.

Remove any debris and excess organic matter that has accumulated on the

bottom and sides of the pond. This can include leaves, twigs, dead plants, and fish waste. Use a pond net or skimmer to remove as much of the debris as possible. You may also need to use a pond vacuumto remove any stubborn debris that has settled on the bottom of the pond. Removing this debris will help improve the water quality and reduce the risk of algae growth.

Don't waste the nutrient-rich water and sludge from the pond.  Instead, as you clean the pond and work your way towards the bottom, discharge some of the water into the surrounding landscape. This water is full of nutrients that can benefit the growth of grass and other plants in the area. So not only are you cleaning your pond, but you're also helping to fertilize the surrounding landscape.

Prioritise removing larger debris like dead leaves and sludge buildup. Don't stress about removing the biofilm or other surface buildup on rocks and plant pots. You don't need to move every single rock to clean behind it - the pressure from your hose should do the trick. Keep it simple and focus on the big stuff!

Once you have removed as much debris as possible, it’s time to drain the pond and give it a good scrub. Use a soft-bristled brush to scrub the sides and bottom of the pond. This will help remove any remaining debris and algae buildup. If you have a large pond, you may need to use a pressure washer to get the job done. Once you have finished scrubbing carry out a final vacuum and then its time to refill the pond. 


Wash and clan out for pump and filters and place them back into position before you start refilling the pond.


Refill the pond with fresh water and Re Pot  Plants

After you have finished cleaning your fish pond, it’s important to refill it with fresh water. This will help ensure that your fish and plants have a healthy environment to thrive in. If your using town water then be sure to add a dechlorinator to the water to remove any harmful chemicals that may be present. If you are using rainwater then add approximately 1 teaspoon of aquarium salt per litre .

A good way to work out how many litres are in your pond is as follows. Get yourself a bucket with litre marks on the inside of it (most household buckets have this). Turn on the tap and time how long it takes to fill the bucket to the 9 litre mark, then turn off the tap. Lets say it takes 1 minute to fill the bucket up to 9 litres.  Then turn on the tap and start filling the pond and time how long that takes to fill completely.  For example if it takes 60 minutes to fill the pond then that means that your pond has 540 litres in it.  Remember your tap can fill 9 litres every minute  so

9ltrs x 60 minutes = 540 litres. 



Cleaning your fish pond is not only important for the health of your fish, but it

Fertilizing a pond plant

also provides an opportunity to tend to your plants. Exam your plants and if they appear pot bound, then report them and also cut and remove any dead foliage. Now is also the time prune or divide any overgrown plants and fertilize all of your water. 

It's important to be gentle with the fish. Once the water has been drained and the cleaning process is complete, slowly refill the pond with fresh water. Before releasing the fish back into the pond, make sure the water is deep enough for them to swim comfortably. This gradual process will help reduce stress on the fish and ensure a smooth transition back into their home.


Add beneficial bacteria and other pond treatments.

 Adding beneficial bacteria and other pond treatments can help maintain a healthy balance of bacteria in your fish pond. Beneficial bacteria supplements

can help break down organic matter and reduce the buildup of harmful toxins in the water. Other treatments, such as algae control products, can help keep your pond looking clear and free of unsightly algae blooms. Be sure to follow the instructions on any pond treatments carefully to avoid harming your fish or plants. 


Maintain regular cleaning and maintenance.

Regular cleaning and maintenance are essential to keeping your fish pond healthy and looking its best. This includes removing debris and dead leaves from the surface of the water, trimming back overgrown plants, and checking the water quality regularly. It’s also important to clean your pond filter regularly to ensure it’s working properly and removing any excess waste from the water. By staying on top of these tasks, you can prevent larger problems from developing and keep your fish and plants thriving in between those big pond clean outs.
