Clarifiers are added to ponds to control Green Water Algae Blooms. The Ultraviolet light within the unit kills the Algae as the water passes over the light. The dead algae are then collected in the filter and can be rinsed once clarity of the pond is returned. UV Sterilizers actually serve 2 purposes, They kill the algae spores and they also kill parasites! We have several that we recommend, just depending on your concerns, fish load, and pond construction.
Carefree UV Sterilizers
These are designed from corrosion-resistant 316-L stainless steel, which prevents toxic chemical emission into the water. All Carefree UV units are made from heavy-duty pipe-not rolled lightweight tubing-to allow for higher psi ratings and long-lasting, rust-free housings. As an added bonus, Carefree UV’s are polished inside the reactor chamber wall to a highly reflective luster/shine. This reflectivity creates more killing power than other units. A bit higher in price, worth the investment due to their construction and Kill Power!
These Clarifier/Sterilizer units are suitable for small ponds up to 6000 gallons using pumps up to 3000 gph.
They are fully submersible units that control water borne algae and spread of disease.
The glowing monitor halo ring, visible from any angle immediately shows that it is working.
Comes complete with 9000 hour 40 watt lamp and water tight quartz sleeve.
Includes transformer and 18ft grounded power cord.
Black color is unobtrusive whether used in or out of water.
Tetra UV Clarifiers
These are plastic molded, green in color and Kill Algae spores that cause green water blooms. Very cost effective and if superb water quality is maintained, you may not wish to invest in the Sterilizer just yet. But if you have a hefty sum of money ties up in fish. I would opt for the Sterilizer! These cannot be submerged!
