Shanda Crystal Clear UV Sterilizer UV-7W Algae Remover Steriliser
UV Clarifiers are installed in-line outside of your pond, usually between your pond pump and your filter. As the water passes over the UV Lamp inside, the algae is killed and it can then be removed by your filter. Highly effective for controlling green water. Keeps your fish pond or ornamental water feature clear year round.
One of the main reasons to invest in a UV pond clarifier is to remove pond algae causing green pond water. The strong UV light emitted will destroy free swimming pond algae at the cellular level, causing them to breakdown and clump together. After they have been broken down they’ll be cleared by the pond filter system, or simply settle to the bottom of the pond and eventually decompose. Since free swimming algae particles are the main reason your pond water is likely green, a UV pond clarifier should greatly improve the clarity of your ponds water after algae levels have been sufficiently reduced. UV clairfiers are also a very safe method of algae removal for fish, so can be used for both koi and goldfish ponds without problems or damage to the eco-system.
UV clarifiers are a great way to remove free-swimming algae, but will not be able to remove larger forms of algae, such as string algae. This kind of algae cannot enter the main chamber of the clarifier so would need to be removed using different methods. Often the best way to deal with an alage bloom is with a combination of solutions, such as using a pond vacuum alongside the UV treatment. If green water is your only concern, a UV clarifier is more than enough for the job.
UV light will also kill both good and bad free swimming pond bacteria that happens to pass through the light. One of the main reasons some pond owners do not like the idea of using a UV pond light is because they’re worried their ponds bacterial balance will be at risk. Even though it’s true that some free swimming bacteria will be removed by the light, the majority of your ponds beneficial bacteria are safely housed within your filter box.
Within your ponds filter, inside the biological media, millions of beneficial bacteria are working to break down harmful substances. This bacteria will not be effected by a UV clarifier, even if your UV pond light is within your filter itself. So basically, even if some floating beneficial bacteria are removed, your ponds filter bacteria population will be stable and continue to provide biological support for your pond.
