You can also use a biological product that helps set natural biological processes in the pond resulting in optimum water quality – Čistič bio jezírek (Biological Pond Cleaner).
This product was developed by the Canadian company NVIRON Biosolutions Inc. in collaboration with PROXIM.
ČISTIČ BIO JEZÍREK (Biological Pond Cleaner) is a well-balanced mix of bacteria and enzymes which efficiently yet gently decomposes organic impurities. The product reduces the nutrient content used by algae for their growth. Once the algae are killed, they serve as food for the bacteria present in the product. The amount of organic sediment on the pond bed is thereby reduced, the water becomes clearer and biological balance is established.
Dosage: 1 kg per 200 m3 water in the pond during a month
