UV
Eco-systems such as ponds require continuous care and maintenance. This ensures that aquatic life (whether it's animals or plants) are healthy and are able to thrive in their environment. Pond UV lights or UV filters are ultraviolet light systems that have been used for years in ponds and aquariums in an effort to control green water caused by algae.
UV systems do not function as filters. That's because they don't actually remove any unwanted material. UV clarifiers, as they are better understood, function as sterilisers because they work simply by killing algae.
