Pond care with microorganisms – biological, sustainable & effective for your pond

When it comes to your own large or small garden pond, it's easy to make mistakes in care. The consequences are often algae growth and blooms, pond sludge, cloudy water and other annoyances.

… It could be so beautiful: clear water in which the sun's rays and the plants are reflected, a few fish occasionally touching the sparkling water surface, and lush green plant life around the shore.

If pond care has been overwhelming you so far, you can relax with BioTeiGa: our products impress with simple, uncomplicated use and effective results. Instead of harmful chemicals, we rely exclusively on biological ingredients that do not burden the environment or animals. You won’t find any fillers or preservatives in our pond care – with us, you get pure concentrates that are simply sprinkled into the water by hand. Experience the power of nature with BioTeiGa pond care in summer and winter.

Analyze water values & buy pond accessories for a beautiful pond

Instead of combining various products from different manufacturers, you’ll find at BioTeiGa products that keep your pond healthy in combination all year round: pond care in winter, spring, summer and autumn.

Optimal water values are the basis for a healthy pond. But how are your pond water values? It’s generally a good idea to check the contents of your pond water from time to time. This works perfectly with our pond water analysis sets. Based on the results, you can correct the water values specifically and tailor pond care accordingly. Whether you need to balance high nitrate levels, enrich oxygen or counteract pollutants – with us, you’ll find treatments and more that make pond care effortless.

You can order and use the products for garden pond care individually. Alternatively, we offer you sets of different products that work together to achieve unbeatable results and optimally care for your pond.

Microorganisms: your guarantee against algae in the pond

Green slime and cloudy water – this clearly indicates an algae problem. While algae are a natural part of a pond’s ecosystem, their growth can quickly get out of hand, disrupting water quality. This not only affects the appearance of your pond but also impacts the health of the fish and plants within it. Many algae killers make big promises, but their effectiveness is often limited and their environmental impact significant. Instead of relying on chemicals, BioTeiGa uses pond care with microorganisms. Our unique blend of different organisms ensures your pond water becomes clear again quickly, allowing you to see your reflection on the surface. The microorganisms, made up of three groups, perform the following tasks:

  • They convert pollutants into gaseous nitrogen, allowing it to escape from the water.
  • They feed on dirt particles, naturally cleaning the pond water.
  • They also consume micro- and macro-nutrients that algae need – acting as direct competitors for food.

All these factors improve water quality and support the self-regulation of your garden pond ecosystem. You can purchase the pond care microorganisms in sets or individually – order now and address the root causes of recurring algae in your garden pond.
