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!
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
To keep your pond healthy, we recommend adding BACTA TAB twice a year. These bacteria help break down waste products in the pond, ensuring clean, clear water.
Use BACTA TAB in the spring as soon as the water temperature rises above 12°C. At that time, the bacteria are most active and support the pond in its post-winter recovery.
In the fall, before it freezes, it is also wise to add BACTA TAB. When the water freezes, many of the bacteria go dormant. Adding the tablets earlier allows them to do their work before the temperature drops.
These two treatments per year will keep your pond clear and balanced, as long as the pond is otherwise properly set up.

BACTA TAB is a valuable tool for balancing small ponds. These bacteria need at least 10 days to settle in properly and do their job. During this time they begin their most important task: improving water quality and reducing algae in your small pond (10 - 1,000 gallons).
However, it is important to realize that bacteria alone cannot solve all the problems in your pond. If the pond is not set up properly, algae can still be a problem. A layer of 5 to 10 cm of porous substrate on the pond floor is essential for a healthy bacteria population. 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. How you can approach this step by step, you can read on our pond check page.
BACTA TAB is 100% safe for humans, plants and animals. This is because the product is made through a 100% natural formula with no chemicals added.
BACTA TAB is created from single-celled microorganisms that act as a natural filtration system in water. They convert pollutants such as ammonium and nitrite into substances that are harmless to nature.
BACTA TAB can be combined with other products without problems. For optimal results, we recommend the use of POND SUBSTRATE pond substrate and INSTA CLEAN soil cleaner.
The pond substrate provides an ideal environment for the bacteria in BACTA TAB to settle and work effectively. Thanks to the porous structure of the substrate, the bacteria spread easily and quickly begin breaking down organic matter and waste products.
INSTA CLEAN acts as a powerful bottom cleaner that removes silt and dirt particles from the pond. This allows the bacteria in BACTA TAB to fully focus on purifying the water without being hindered by excess dirt on the bottom.
The combination of these products ensures a healthy and stable pond environment in which algae problems and cloudy water are minimized.
It is also important that the pond contain enough different types of aquatic plants so that all elements work together effectively for a year-round clean pond.

Our BACTA TAB bacteria are a valuable tool for balancing your pond. These bacteria need at least 10 days to settle in properly and do their job. During this period they start their important task: improving water quality and reducing algae.
A green or cloudy pond after adding BACTA TAB is normal. This is because the bacteria actively loosen soil debris; the cloudy color disappears on its own.
However, it is important to realize that bacteria alone cannot solve all pond problems. Without proper setup, algae can return.
A layer of 5 to 10 cm of porous substrate on the bottom is essential, along with sufficient aquatic plants, such as marsh plants, oxygen plants and water lilies. These elements allow the bacteria to do their work optimally and help prevent pond problems for good.
A good balance between these components is crucial for a healthy pond. Each aspect strengthens the other, and only by using them together will you achieve the desired results.
Discover how to do this step by step? Then check out our pond check.
The cloudy or dark color after addition of BACTA TAB can occur because silt is released from the pond bottom, which is then broken down by the bacteria in BACTA TAB. If insufficient aquatic plants are present to absorb the released waste, the water may become temporarily cloudy. This is a normal process and usually disappears within about 10 days.
To prevent this cloudy color from returning, it is important to properly set up the pond. A layer of 5 to 10 cm of porous substrate on the bottom is essential. It is also important to have enough aquatic plants , such as marsh plants, oxygen plants and water lilies. These support the bacteria in their work and help prevent murky or dark water.
A good balance between these elements is crucial for a healthy pond. Each component reinforces the other, and only by using them together will you achieve the best results.
Want to learn step-by-step how to do this? Do the pond check.
A green oil film on the water after adding BACTA TAB is normal. This is because the bacteria actively loosen bottom debris, causing wastes to float to the water surface. This problem usually resolves itself within about 10 days.
However, it is important to know that bacteria are a useful tool, but not the only solution to all pond problems. Without proper pond design, algae can easily return.
A layer of 5 to 10 cm of porous pond substrate on the bottom is essential. In addition, it is important to have sufficient aquatic plants such as marsh plants, oxygen plants and water lilies. These plants support the work of the bacteria and help prevent pond problems throughout the year.
