A UV pond filter will help reduce algae in your pond. The Ultraviolet light will make the algae stick together, and then it can be passed through the pond filter and removed.
UV Pond Filter and Biological Filtration: A Winning Combination
When you use a UV pond filter with Biological Filtration, you are ensuring that the algae will be clumped together, and then the bacteria can feed on them, breaking them down. This will ensure that your pond is clean, clear, and healthy for all of your living organisms.
