UV-C radiation and ozone together form the perfect combination for making pond water immaculately clean and rich in oxygen. Ozone and UV-C kill Algae, viruses & bacteria.
The UV-C radiation also completely breaks down any residual ozone. The equipment produces ozone which is 100% safe there is no ozone left in the water flowing out. The UV-C redox increases the capacity of the pond filter and then riches the pond water with oxygen thus creating a healthy environment for koi and plants.
