Oxygenating plants and a bottle of Bacta clear
Purchased: Pond clear package - M
My pond was quite murky, so after a good conversation with Simon, I decided to follow the advice: more oxygen plants and a bottle of bacteria. I ordered the recommended package, but after four days no improvement was visible. Full of disappointment, I contacted customer service. They advised me to be patient and give the process 2-3 weeks. Although I had my doubts about it, I decided to wait anyway. And what turned out? After two weeks, the water started to clear and I even saw frogs that I had never noticed before! Thanks team vdvelde, and apologies for my impatience!

Plants are growing much better now and water is crystal clear
Purchased: POND SUBSTRATE pond substrate - 40 liters
Last year I had a landscaper install a plant filter at my swimming pond, recommending lava and some plants from the local garden center. Unfortunately, things went completely wrong; the plants died one by one and I suffered an algae infestation. After contacting customer service, I was advised to replace the lava with pond substrate and order some more plants. Now, several months later, the plants are growing well, and my filter is finally free of algae.

My little city pond
Purchased: Complete Pond Package - S - Red
I had been dreaming of having a pond in my urban garden for some time, but it always seemed like such a hassle. Online I found a complete package and decided to take the gamble, although I was skeptical about the quality of plants sent through the mail. But to my surprise, everything was delivered neatly and well-packaged. Within no time I had my pond set up. To my delight, after only two months I saw the first water lily bloom, and as icing on the cake I discovered salamanders in my pond. No idea how they got there, but it only adds to the joy. Truly enjoying it!

A must for anyone with a pond (large or small)
Purchased: Simons Pond Advice Book
This book completely meets my expectations. A great guide with lots of great tips on pond construction, pond plants and design.
Highly recommended purchase on my part.
Great book!

Blue lily: beautiful!
Purchased: Hardy Blue Water Lily - Nymphaea Blue Queen
Thank you very much for the generous delivery of the swamp iris "Blue Lis".
The new plants have been planted and I am curious to see if they will bloom this year.
There is good news about the water lily "Blue Queen": It is also blooming here in blue - and how beautiful!

Removing soil sludge without a vacuum cleaner
Purchased: Soil Dirt Pond Removal Package - M
After years of accumulation by fish, quite a bit of silt had accumulated in my pond.
At first I thought about a pond vacuum cleaner, but after contacting customer service I opted for the bottom debris removal package. I was skeptical, especially because the water became murky the first week. But after a month, the silt has reduced considerably. No hassle with a vacuum cleaner, and great results!
I am a fan.

water lilies for more biodiversity
As lovers of greenery, we were looking for a sustainable addition to our project. Van der Velde's water lilies were a hit! With DROP & GROW, it was really simple: plant and enjoy. We asked for different varieties and this was no problem either. Delivery was perfect. Within a week we already saw leaves above water, and meanwhile there are several flowers blooming. Both we and our customer are very enthusiastic.

Oxygen plants save my fish
Purchased: Oxygen Plants Pond Package - L
My fish were gasping for air, so I was looking for an air pump. Then I read that oxygen plants could also solve this problem. I ordered the package that fit my pond, and now my fish are swimming around carefree again. Additional plus: my pond water is much clearer. Fish happy, me happy!
Greta Schultze
Very happy with my small pond
Purchased: Complete Pond Package - XS
This handy kit helped me set up my mini pond quickly. Everything you need is included! The service and advice were top notch, much better than at the garden center where no one really knows anything.

From maintenance to an organic swimming pond
Purchased: Complete Plant Filter Package - L
I was tired of constantly cleaning the pump, so I decided to convert my pond to an organic swimming pond. With the plant filter package from vdvelde.com, it worked out perfectly! Now I enjoy a beautiful, natural filter and lovely swimming water.
Frequently Asked Questions
After adding INSTA CLEAN, pond water may become temporarily cloudy. This is because the product begins to break down suspended particles and organic waste in the water.
INSTA CLEAN is a valuable tool for cleaning up bottom sludge in an environmentally friendly way. However, it is important to realize that INSTA CLEAN alone is not enough to solve all the problems in your pond. If the pond is not set up properly, algae may still occur. A layer of 5 to 10 cm of porous substrate on the pond bottom is essential. In addition, sufficient aquatic plants should be present, such as marsh plants, oxygen plants and water lilies. These allow the bacteria to do their job optimally and help reduce the green color of the water and algae.
A good balance between these elements is crucial for a healthy pond. Each aspect reinforces the other, and only by using them together can you achieve the desired results. You can read exactly how to do this step by step on our pond check page: pond check.

Turbidity would usually decrease within 48 hours as INSTA CLEAN does its work. Ensure good circulation and aeration to speed up the process.

Yes, some degree of turbidity may occur with any addition, especially if there is a lot of organic waste in the pond. This is a normal part of the cleaning process.
However, it is important to realize that the pond must be set up correctly for INSTA CLEAN to do its job properly. If the pond has not been set up properly, INSTA CLEAN is only a temporary solution to combat algae. If the pond is set up correctly, you will get rid of algae once and for all.

INSTA CLEAN is ideally suited for use in swimming ponds, as it is a 100% organic product that is completely safe for humans, plants and animals. Combined with BACTA CLEAR, they form the ideal duo for a clean and healthy pond. While INSTA CLEAN effectively cleans the pond bottom, BACTA CLEAR focuses on purifying the water by removing waste products. Together, they work toward the same goal - a clean, clear pond - but each in a unique way, making them complement each other perfectly. Check out the combo deal here.

The cloudy color of the water can be caused by the bottom being full of silt, which is not cleared away by the plants. The pellets INSTA CLEAN loosen this silt, but if there are not enough plants to clean up the waste, it can make the water cloudy.
It may take 10 to 14 days for this to subside. If there are many oxygen plants in the pond, this may be remedied sooner.
INSTA CLEAN is a valuable tool for balancing your pond and cleaning the pond floor, but it is important to realize that INSTA CLEAN is a temporary solution and not a long-term one. If the pond is not set up properly, algae can return just like that. A layer of 5 to 10 cm of porous substrate on the pond bottom is essential. In addition, sufficient aquatic plants must be present, such as marsh plants, oxygen plants and water lilies. These will keep the algae and bottom silt away for a long time.

How often you need to add INSTA CLEAN depends on the amount of silt on the bottom, any algae, or cloudy water. If the water is not clear, repeat the treatment until you achieve the desired results.
INSTA CLEAN needs several weeks to work optimally. Always follow the recommended dosage on the package: 500 ml (1 measuring cup) per 1,000 liters of water.
If algae keeps coming back repeatedly after using INSTA CLEAN, then your pond probably contains too few plants, and mainly not enough oxygen plants.

Have you set up your pond with enough substrate, marsh plants, water lilies and pond bacteria? If so, you probably don't have enough oxygen plants in your pond. Choose additional oxygen plants to get rid of your algae for good.
No, there is no need to empty the pond before adding INSTA CLEAN. You can simply sprinkle the granules evenly over the surface of the water. They will then naturally sink to the bottom, where they will begin to clear away the bottom silt and do their job. This makes using INSTA CLEAN very easy and effective, without having to empty the pond.
Keep in mind that INSTA CLEAN is a temporary solution for bottom mud, because the pond must be set up correctly for the pond to remain free of bottom mud. You can check how to set up your pond correctly using the pond check.
The best time to administer INSTA CLEAN is in spring and fall, when your pond could use some extra support. Should there be a lot of algae growth in the summer, you can use it even then for effective algae control.
You can easily sprinkle the pellets of INSTA CLEAN evenly over the surface of the water. They then sink to the bottom, where they effectively tackle the dirt.
For best results, we recommend using about 500 ml per square meter of water surface.
INSTA CLEAN has a shelf life of 1 year after opening. Unopened, the product will keep for years.
INSTA CLEAN can be added even at lower temperatures and continues to contribute to improved water quality in the pond. Even in the winter months, it supports water clarity and helps keep the pond clean.
