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!

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!

Frequently Asked Questions
Pond clarity can be affected by several factors, including the presence of algae, water quality and the balance of bacteria in the pond.
With murky water, it is important to identify the cause. This can range from algae blooms to a lack of beneficial bacteria. Plenty of oxygen plants and a bottle of Bacta Clear are the solution.
Keeping your pond algae-free is achieved by maintaining a healthy balance between pond plants, pond fish and bacteria in the pond. Using Bacta Clear helps keep algae away.
It depends on the extent of the problem and the solution used. With oxygen plants and Bacta Clear, improvement can be seen within a few weeks.
The pond clearer package includes 4 types of loose oxygen plants; elodea densa, hornwort, crabgrass and moss balls. These aquatic plants grow just below the water surface so they keep the sun out of the water in the summer and add oxygen to the water. The convenience of these plants is that you throw them loose in the pond and you do not have to worry about them.
Float algae in the pond
Are you standing by your pond and notice that the water has turned murky and green? This is due to floating algae, also known as green water algae. It is frustrating, difficult to remove and it can seriously affect the health of your pond.
We are ready to help you!
With our years of experience, we have created the Float Algae Control and Prevention Package, specially designed to naturally clear your pond and keep it free of waste products. This package ensures that algae doesn't have a chance, without the need for pumps, filters or chemicals. Invest in a natural look and limited maintenance, and enjoy a healthy, clear pond year-round.
Why isn't your pond clear?
A question often asked, "Why isn't my pond clear?" Cloudy water in a pond can have several causes, such as excess algae or a deficiency of beneficial pond bacteria. Whether you want to make a green pond clear or keep a shallow pond clear, we'll give you the tips you need to achieve this result easily, quickly and completely naturally.
How is a green pond created?
A murky pond is out of balance and this can have several causes, including excessive fish stocking, not enough oxygen plants, lack of proper pond bacteria, warm weather and the presence of waste products. When the self-cleaning ability of the pond water decreases, pollutants can accumulate and stimulate the growth of floating algae, which can cause the pond to become green and cloudy. This can lead to disruption of pond plants and pond wildlife in the pond.
Clear your pond with oxygen plants
Oxygen plants are essential for any kind of pond. Not only do they help clear the green pond, but they also keep the pond algae-free. By creating a balance between oxygen plants and algae, you can prevent murky water in your pond and even achieve a clear pond without a pump, filters or water improvers.
What is floating algae?
Float algae, also known as phytoplankton or water bloom, is a type of algae that can form in excessive amounts in ponds and turn the water a murky green color when the pond is not properly set up. These algae float freely in the water and can multiply rapidly under favorable conditions, such as warm weather, plenty of sunlight and nutrients due to the absence of sufficient oxygen plants. If overgrown, they can turn the water cloudy and green, leading to oxygen deficiency in the water and health problems for pond fish and other pond animals. It can also hinder the growth of aquatic plants . Therefore, to prevent or reduce floating algae, it is very important to set up the pond correctly according to our step-by-step plan: Read how to do this here.
What does floating algae look like?
The single-celled organisms of floating algae float loosely through the water, hence the name. They are a genius at multiplying quickly, turning your pond green in no time. The murky water becomes less and less transparent, so much so that eventually you can no longer see the fish and pond plants.
How do floating algae form?
Floating algae occurs when the natural balance in the pond is disturbed, creating space for these and other types of algae, such as filamentous algae. Especially in newly constructed or improperly designed ponds, clear water can quickly turn into a green soup. Oxygen plants are crucial in this context: they absorb nutrients from the water, preventing floating algae from flourishing. By planting enough oxygen plants, you keep the pond clear and prevent algae growth.
What to do about floating algae?
aquatic plants
Adequate CO2 is essential for a healthy pond. Various aquatic plants, such as pickerel weed and flag iris, contribute to this by releasing CO2 into the water. water lilies and marsh plants also take CO2 from the air. Strengthen this natural balance by adding good pond bacteria in the spring, which optimizes the CO2 concentration in the water.
pond substrate
pond substrate forms the ideal foundation for your pond, in which aquatic plants can firmly take root and function optimally. This substrate consists of coarse, porous stone grains that serve as home base for pond bacteria and aquatic plants. Using substrate creates a natural pond that remains maintenance-free without pumping systems and filters.
Sufficient oxygen plants
Always have plenty of oxygen plants in your pond; they absorb nutrients and keep the water crystal clear. For a solid foundation for these plants, pond substrate is essential. Check the growth of your oxygen plants regularly; reduced growth can indicate the presence of floating algae which means you need to add more oxygen plants. To know what you need and how much, read our step-by-step plan.
Removing floating algae
Speed up the control of floating algae with our biological algae remover, Bacta Clear, which is also effective against thread algae. Note that this does not prevent the growth of new algae once the effect diminishes. Restoring the natural balance in the pond is essential. You can also remove some algae manually or with a scoop net.
How to get clear pond water quickly ?
Set up your pond correctly according to our step-by-step plan prepared for pond experts. Clear pond water in 6 steps:
- Start with the Basics: pond substrate Create a robust substrate for your pond with pond substrate. This serves as a natural filter, attracts beneficial bacteria and provides a solid foundation for plant roots. For a healthy pond, we recommend 40 liters of substrate per m², giving you an 8-10 cm layer of substrate.2. Oxygen Plants are Essential: Oxygen plants clarify the water and prevent overheating, thus limiting algae blooms. We recommend a minimum of 10 to 12 individual oxygen plants per m³, plus 2 baskets of 4 plants per m² for optimal results.3. water lilies: water lilies are not only beautiful, but also functional, protecting from sunlight and providing shade for fish. For best results, place at least 1 water lily per 0.5 to 3 m².4. Purify with Marsh Plants: As natural purifiers, marsh plants are crucial, especially without a pump or uv filter. We recommend a minimum of 2 baskets of 4 plants per 1 m² for keeping your pond clean.5. Integrate Other aquatic plants: Plants such as sweet flag and pickerel weed filter the water and reduce waste, thus promoting a healthy ecosystem. As with marsh plants, we recommend at least 2 baskets of 4 plants per 1 m².6. Pond Bacteria: Start your pond off on the right foot with pond bacteria. Our choice, Bacta Clear, adheres to the pond substrate, helping to maintain a clear and healthy pond.
Is floating algae dangerous?
Excessive growth of floating algae (also called algal blooms) can be problematic for a pond. It can compete with other plants for nutrients and light. At night and during algae die-off, oxygen is extracted from the water, which can lead to a drop in the oxygen level in the water. This can be harmful to fish and other aquatic animals.
