The sustainable suppression of mass algae development is an important prerequisite for a biological balance in the water. Algosol acts actively against all types of algae and reliably curbs mass algae development and the one-sided proliferation of individual algae species in ponds. Algosol achieves excellent results, particularly with single-celled green algae and in the preventative treatment and suppression of blue-green algae.

Algosol does not kill algae immediately, as their decomposition would otherwise lead to an enormous oxygen depletion. The active ingredients in Algosol lead to a slow death of the algae, which means the effect may take several days. This consciously preserves the biological balance in the pond. Additionally, the light filter SpektroSorp reduces the light yield of the algae and thus their photosynthetic activity. The algae gradually "starve".

Algosol prevents the harmful effects of algae metabolism, such as the excessive consumption of carbonate hardness and strong pH fluctuations.

With regular use, renewed algae growth is effectively prevented.

Algosol is free from humic acids and does not affect the performance of your filter.  

Our application and dosage recommendation

For optimal results, apply in the morning. Dilute the dose with at least 20 times the amount of pond water (e.g., in a garden watering can) and distribute evenly throughout the pond. Avoid contact of the undiluted product with aquatic plants.

When used correctly, there are no known side effects on fish, plants, and amphibians.

Fish can remain in the pond during treatment. The pond water remains suitable for use as irrigation water even after the Algosol treatment.

50 ml of Algosol per 1,000 liters of pond water. After 2 to 3 weeks, re-dose with the same amount to increase efficacy and combat germinating permanent forms. For heavy algae infestation, the use of Algosol forte is recommended.

For blue-green algae infestation: 10 ml of Algosol per 1,000 liters of pond water for 5 consecutive days.

In case of accidental multiple overdosing of Algosol, harm to animals and plants in the pond may occur. In this case, add TeichFit to the pond, which causes a substantial neutralization of the active ingredients in Algosol. 

Interesting to know

At the recommended dosage of 50 ml of Algosol per 1,000 liters, there is an average of 175 µg of copper sulfate in every liter of pond water.

Use algicides carefully. Always read the label and product information before use.
