Combat biofilm in your swimming pool, pond or hot tub by using an NDV Ultrasonic device.


Perpetual issues, we’ve got the solution

For more than a decade we’ve embedded research to understand the reactions and use of liquids, starting from the root cause of our problems. This root cause is the biofilm. We have unravelled this micro-organism and incorporated the findings into our product as a craft. The most averting problems are listed here.

Green water & walls

The growth of algae is an issue that all pool owners face since it turns water green. They start small but can quickly become a plague. Algae commences from forming its roots in the biofilm. It uses the biofilm as its food source to start growing. Without it, it will never be present in a pool.

Slippery floor

A slippery floor can be a dangerous part of a pool. It can easily make people fall and harm them. The slipperiness is coming from the biofilm. The biofilm secretes a layer of slime that builds up and can be felt by humans and animals.

pH-level fluctuation

Since still and circulating water experiences fluctuating pH-levels, the owner of a pool is required to check its pH-levels at least three times a week. According to the results, a supply of stabilisers is necessary. This often takes a lot of time and effort.

Frequent chemical use

In pools, chemicals are frequently used to combat the presence and growth of bacteria and reduce the germ count. Since chemicals only eliminate bacteria temporarily, they need to be monitored and refilled monthly. This can become labour intensive and dangerous for your body and the natural environment.


Water creates biofilm in swimming pools, ponds or hot tubs. This generates a slippery layer on the floor and walls of the tub in which algae and bacteria can easily develop. An NDV Ultrasonic device kills these organisms without the use of chemicals, leaving your water cleaner and healthier. This device not only works in tubs, but also cleans boilers, water collectors and pipes, resulting in fewer pipe breaks and less bacteria growth.

Installing the NDV Ultrasonic devices

NDV Ultrasonic devices require with a specific glue that is included in every order. This glue allows the vibrations to pass through. You can easily install the device yourself. If you choose to do so, we will check and approve the installation.

I would recommend NDV Ultrasonic to everyone with a sailboat. It saves me on yearly maintenance costs in a eco-friendly matter.

Fishing Pond
I had a lot of issues with thread algae in my pond but after one month with NDV Ultrasonic, I could easily scoop out the algae and could finally see the bottom. After 6 years, I never experienced any problems anymore.

I had a slight bit of ‘green’ on some of the floor/walls of my pool. This now seems to have gone, forever.

With NDV Ultrasonic, my antifouling has been there for 5 years straight, and the boat is still clean without being replaced or taken out of the water!

The device installs quick. Now I don't have to clean my jacuzzi every two months and can leave it as it is without adding any chemicals to it.

I had a fully personalised service for my swimming pond. A fantastic product with great results, and it doesn't harm my fish but actually creates a better environment for them!
