UV filters
Why is Ultra Violet (UV) filtration important?
Single cell algae form green water in garden ponds. This is not only unpleasant to look at, but at the same time contribute to lowering the “kh” value which is so important to fish health, and to the nitrification process within the filter system. Algae’s also lower oxygen levels, whilst meanwhile increasing “ph” levels – both of which are undesirable. The use of Ultra Violet is a safe technique used for obtaining clear water, and unlike many chemicals detrimental effects or pollution is impossible. In addition general plant and pond life are unaffected with a UV.

The actions of ultra violet light onto single cell algae’s does not actually kill them, but converts the algae’s DNA structure to the point where they flocculate together, and thus form larger particles which will not so easily pass through the mechanical filter mediums. The amount of sunlight which the pond receives is the biggest of factors in the promotion of algae's, and for such reasons the selected size of a UV unit should take such environmental aspects into account.
UV's are also an established technique used to control the growth of harmful bacteria and pathogen in your pond.
