Best Pond UV sterilizer Reviews | Pond UV Clarifier Review | Control green fish pond water

how to clear green Pond Water...

Maintaining crystal clear water, free from the dreaded green water algae bloom is the aim of the vast majority of us pond keepers. Whilst a pond with some suspended green algae may not necessarily be a bad thing it will detract from the idea of the fish pond i.e. keeping and being able to see your Koi, goldfish and other pond inhabitants.

Suspended single celled algae also known as floating algae or pea soup algae is a blight for many a pond keeper, particularly during the warm summer months when there is an abundance of pond nutrients and sunlight.

In my opinion a Pond UV sterilizer or UV Pond Clarifier is the best all round method of controlling algae in water. The terms UV sterilizer and UV Clarifier are used to mean the same thing on this site although there are actually some differences.

For our purposes though please take them to mean the same thing.

Although there are other green water pond treatment methods including shading, using pond algaecide products, using aquatic plants and other chemical treatments, I would recommend UV sterilization (UV Clarification) because it will cost you less money in the long run as well as save you lots of time and effort.

Is a Pond UV Sterilizer The Same As A Pond UV Clarifier?

Many pond keepers and manufacturers use the above terms to describe their product, without inferring any difference. There are however some differences.

A Pond Sterilizer in essence sterilizes pond water, not only destroying green algae cells but also parasites, bacteria and other living organisms that are found circulating around your pond. UV sterilizers are usually used in Koi ponds where there are larger volumes of water.

A pond UV clarifier kills algae cells by bombarding them with UV rays, causing them to flocculate (clump together), making them easier to remove by your pond filter or pond vacuum. Pond clarifiers also destroy some floating organisms, but not to the same extent as a UV sterilizer.

Why Do You I Need A Pond UV Sterilizer?

A UV pond sterilizer or UV pond clarifier is an essential piece of pond keeping equipment for any pond keeper wishing to maintain a healthy algae free pond eco system. There are a myriad of chemical algaecides on the market but there usefulness is short lived and in some instances they interfere with the beneficial bacteria living on the pond filter media.

Pond UV sterilizers utilize UV rays to destroy floating algae along with many microscopic water borne parasites, bacteria and other unwanted organisms.

A UV sterilizer or UV clarifier will not interfere with the beneficial Nitrosomonas and Nitrobacter bacteria living on your pond filter media and is by far the best long term algae control method.
