About this product
The Oase Biosmart Set 7000 is easy to install and maintain. Thanks to the cleaning handles, you can easily squeeze out the filter sponges, and the bottom drain ensures that contaminated water does not flow back into the pond. The flow-through filter features handy indicators for water temperature and contamination levels, so you always know when maintenance is needed.
What makes this product special
This filter system features a built-in 9-watt UVC lamp that effectively combats floating algae and pathogens, keeping your pond water clear and healthy. The unique water flow design within the housing also provides additional oxygenation, which is essential for the health of fish and other aquatic life. The system is easy to bury for a neat appearance.

The Oase Biosmart 7000 is designed with sustainability in mind. The filter provides mechanical and biological filtration thanks to its filter sponges, which ensure thorough water purification. The dark, sealed lid creates a quiet environment and promotes an optimal nitrification process, keeping your pond water clear for a long time.

The water is finally clear
Purchased: Native Pond Kit 1,500–3,000 L
No matter what I tried, the water in my pond just wouldn't clear up. After exchanging a few emails, I decided to order this complete kit, though to be honest, I wasn't very confident it would work.
The delivery was in good condition and the plants looked healthy. Not much changed during the first few weeks, but after about a month, the water slowly began to clear up.
Now the pond is really in perfect balance. The plants are growing well, and I can even see frogs among the leaves again. I'm really glad I gave this a try.

Plants are growing much better now, and the water is crystal clear
Purchased: STEP ONE Pond substrate
Last year, I had a landscaper install a plant filter in my swimming pond, and he recommended lava rock and some plants from the local garden center. Unfortunately, it all went wrong; the plants died one by one, and I ended up with an algae infestation.
After contacting vdvelde, I was advised to replace the lava rock with Pond substrate to order some additional plants. Now, a few months later, the plants are growing well, and my filter is finally free of algae.

My little city pond
Purchased: Pond Kit Red 100-400L
I’d been dreaming of having a small pond in my city garden for a while, but it always seemed like such a hassle. I found a complete kit online and decided to take a chance, even though I was skeptical about the quality of plants sent by mail. But to my surprise, everything arrived neatly and securely packaged. In no time at all, I had set up my little pond. To my delight, I saw the first water lily bloom after just two months, and as the icing on the cake, I discovered salamanders in my pond. No idea how they got there, but it just makes it even more fun. Truly a joy!

A must-have for anyone with a pond (big or small)
Purchased: Simons Pond Advice

I highly recommend buying this.
Great book!

Blue lily: beautiful!
Purchased: Blue Water Lily
Thank you very much for the generous shipment of the marsh irisIris blue”.
The new plants have been planted, and I'm curious to see if they'll bloom this year.
There’s good news about theBlue queenwater lily: It blooms in blue here too—and it’s absolutely stunning!

Removing floor debris without a vacuum cleaner
Purchased: POND CARE Maintenance Kit
After years of accumulation caused by fish, a significant amount of silt had built up in my pond.
At first, I was thinking about getting a pond vacuum, but after talking to customer service, I decided to go with the bottom debris removal kit. I was skeptical, especially since the water got cloudy during the first week. But after a month, the sludge has decreased significantly. No hassle with a vacuum, and a great result!
I’m a fan.

Water lilies greater biodiversity
Purchased: Native Water Lily Field XL
As plant lovers, we were looking for a sustainable addition to our project. The Water lilies vdvelde turned out to be just what we were looking for. Planting the lilies was also a lot of fun. We had requested different varieties, and that wasn’t a problem at all. The delivery was handled professionally, and everything looked great. Within a week, we already saw leaves emerging above the water, and now several flowers are blooming.
Both we and our client are extremely pleased with the result.

Oxygen-producing plants save my fish
Purchased: Oxygenating Plants Package 1,500–3,000 L
My fish were gasping for air, so I looked for an air pump. Then I read that oxygenating plants could solve this problem too. I ordered the package that fits my pond, and now my fish are swimming around carefree again. An added bonus: my pond water is much clearer. Happy fish, happy me!

I'm really happy with my little pond
Purchased: Pond Kit Red 25-90L
This handy kit helped me set up my mini pond in no time. It comes with everything you need!
The service and advice were excellent—much better than at the garden center, where nobody really knows anything.

From maintenance to an organic swimming pond
Purchased: Plant Filter Package 8–12 m²
I was tired of constantly cleaning the pump, so I decided to convert my pond into a natural swimming pond. With the plant filter kit from vdvelde.com, it turned out perfectly! Now I enjoy a beautiful, natural filter and lovely swimming water.
