View full detailsString algae can be a real nuisance for owners of ponds and natural ponds. They grow quickly and can invade aquatic plants, making the water dirty and unhealthy. Fortunately, there are products such as Colombo Algisin , which offer a precise and effective solution to control the growth of string algae in your pond.
Colombo Algisin Product Features
Algisin is an energetic and precise solution against filamentous algae . It is available in three different packagings (water tester included):
- Algisin 1,000 ml for 10,000 liters of water
- Algisin 2,500 ml for 25,000 liters of water
- Algisin 5,000 ml for 50,000 liters of water

In just a few days, Algisin starts to work against filamentous algae. And after 15 days, the pond will be completely free of algae. Thanks to its enzymatic effect , the algae will be constantly deprived of food, which will weaken them and cause them to die naturally . You can then easily remove the dead algae using a fine-mesh net or a landing net .
Directions for use
For optimal efficiency, don't forget to carefully check the different water hardnesses and other parameters of the pool. A water test strip is included in each pot, but a case like the Colombo Test Lab remains a must!
It is also important to clean the filtration system regularly and add pond bacteria , which help maintain the biological balance of the water. Algisin is a safe product to use and a water test strip is included in each pot to allow you to treat safely.
Finally, choose the packaging that suits the size of the pool for precise and effective treatment.
