Ultra Violet Clarifiers

Filtration takes out the bulk of wastes from pond water, but won't stop it going green with algae, ideally you should have an Ultra Violet clarifier installed in the system. Strong UV light destroys algae and germs cells and prevents it from reproducing. This leaves you with clear, healthy pond water free of algae and disease causing germs.

Many pond filters have UV clarifiers built into them, for more UV clarifiers, see the Pond Filtration category.
