Passing your pond water through a UV the light breaks down the algae and causes them to stick together in larger clumps that your pond filter can trap and remove.



When deciding on the best UV clarifier it is important to consider how durable it is and how long it will last.

You can choose from a range of build materials such as plastic, stainless steel and titanium. Plastic bodied UV clarifiers tend to be cheaper, but are less robust than others. Titanium UV clarifiers on the other hand offer greater durability, they are tough and are immune to corrosion making them virtually indestructible and giving greater longevity.  Of course, this performance comes at a price and Titanium UVs can be significantly more expensive than plastics and the mid range stainless steel UV clarifiers,
