The Tetra ultraviolet clarifier works by exposing single celled algae to very high levels of ultraviolet light as the pond water containing them is pumped through the unit. The ultraviolet radiation not only kills the algae but causes it to clump together. These clumps can then be easily removed by your pond filter, water clarity is dependent upon the pond filter removing the dead algae.
