Most people realise what their pond filters and pond pumps do in their pond but are still a little in the dark regarding ultraviolet pond lights (pardon the pun).

Why should I use an ultraviolet pond light?

Ultraviolet (UV) pond lights can be called many things. You may have heard the terms pond lamps, pond clarifiers, or even sterilisers. The terms can mean different things but in general a UV pond light is used to eradicate green water problems. You may have seen ponds in the past that look like a ‘pea soup’. This has happened because of an algal bloom, if your ponds eco system is not balanced, algae can start to grow rapidly. This phenomenon is mostly seen in the spring to summer months and hence this is when your UV pond light will do most of its work. You can get chemical treatments that can get rid of your algae but most are only a short term solution and the algae will quickly re-colonise your pond.

There are different types of UV pond lights available and a quick look on your aquatic retailer’s website will give you an idea about the costs involved in installing one.
