Green, murky water in your pond? Here’s the solution!

Grünes trübes Wasser im Teich? Das hilft!

Green, murky water in your pond is the nightmare of many pond owners. The unsightly appearance and greenish cloudiness of garden ponds are caused by suspended algae.

Would you like to quickly restore clarity to your pond and combat suspended algae in the long term? The BioTeiGa system helps you tackle the root causes of green water—naturally, highly efficiently, and cost-effectively.

The best part about our solutions: In the future, you’ll only need to spend 20 minutes a month on your pond, which will then maintain its biological balance.

Over 50,000 satisfied customers can confirm this!

Key points at a glance

  • The cause of green pond water is the excessive growth of suspended algae.
  • Conventional solutions like algaecides do not combat green, murky water in the long term and harm other pond inhabitants.
  • With the BioTeich Clear-Water Set, you can permanently, environmentally friendly, and cost-effectively combat suspended algae.

Suspended algae: the cause of green, murky water

Pond owners notice it every year: In spring, the pond water appears cloudy and greenish. The culprits are suspended algae. Suspended algae belong to the green algae family and form an important part of a healthy pond as pond plankton.

They provide food for tiny organisms like water fleas and are key oxygen suppliers for other pond inhabitants. However, when they multiply excessively, they turn the pond water green. The algae bloom not only looks unsightly but also endangers the pond’s ecological balance.

A slight cloudiness in pond water is no cause for concern. In spring, other pond plants are still inactive, so the available nutrients are absorbed by the algae. Once the other pond plants grow, the nutrient supply for suspended algae decreases.

In a healthy pond, a balance is established, preventing the mass proliferation of suspended algae, and the pond water becomes clearer again. However, if the garden pond falls out of ecological balance, an algae bloom occurs.

Factors contributing to excessive algae growth

The cause of algae blooms is an excessively high phosphate level in the water. When phosphate levels exceed 0.035 milligrams per liter, algae multiply rapidly, leading to an algae bloom.

Elevated phosphate levels in water occur for the following reasons:

  • Sunlight warms the pond water.
  • Nutrients are present in excess, e.g., due to dead plants or overfeeding fish.
  • There is a lack of natural predators and nutrient competitors, such as water-purifying microorganisms.
  • The water is oxygen-deficient.
  • The algae bloom prevents sunlight from reaching deeper water layers, impairing the photosynthesis of underwater plants and disrupting the ecological balance in the garden pond.

Algaecides – not a long-term solution

In desperation, many pond owners turn to algae killers. These agents, known as algaecides or biocides, destroy the organic part of suspended algae. The algae then either clump together at the water’s surface and can be removed with a net or sink to the bottom.

The problem: Algaecides also destroy other single-celled organisms in the pond water. If dead algae remain at the pond bottom, they release nitrate and phosphate, which serve as nutrients for surviving algae. This further disrupts the pond’s biological balance.

So-called UVC clarifiers are gentler. A UVC lamp destroys the structure of the algae, and a filter removes the remaining debris. However, like algaecides, a UVC filter does not address the root cause of algae blooms: an excess of nutrients and unfavorable water conditions.

Fight suspended algae – naturally, quickly, and cost-effectively!

With the BioTeich Clear-Water Set, you can permanently combat suspended algae—completely naturally. The set contains four different products that restore the biological balance in your pond.

Benefits of the BioTeich Clear-Water Set:

  • stabilizes key water parameters (kH and pH),
  • ensures optimal mineralization of your garden pond,
  • neutralizes harmful pollutants,
  • lowers phosphate levels,
  • adds a unique blend of microorganisms to the water that compete with algae for nutrients.

The result: Suspended algae disappear, and the pond water becomes clear again. This prevents algae growth in the long term.

Clear water with just 20 minutes of pond maintenance per month!

Want green pond water to be a thing of the past? You don’t have to become a slave to your pond. Prevent algae growth in a smart way and invest just 20 minutes a month in pond care!

How to keep pond water clear:

Remove pond sludge regularly!

Dirt and dead plant matter settle as pond sludge at the bottom of the garden pond. The nutrients bound in the sludge eventually return to the pond water, promoting algae growth. With the BioTeich Sludge-Removal Set, you can naturally break down pond sludge.

Use fast-growing pond plants!

Fast-growing pond plants reduce the nutrient supply for suspended algae while providing essential oxygen. Suitable plants for garden ponds include hornwort, waterweed, coontail, or water screw. We recommend planting them in BioTeich VitaTon.

Shade your pond!

If your garden pond is exposed to full sun all day, excess nutrients form, and algae growth spirals out of control. Floating-leaf plants and shade sails provide shade and prevent the pond water from warming up.
