Tetra GreenFree UVC18 (MPN 19521-01)

on Clarifier

The reflective insert increases UV exposure and prevents internal UV degradation of the plastic housing.

How does UV work?

  • Pond water containing single-cell algae is pumped into the clarifier.
  • Ultra-violet light destroys single-cell algae's ability to reproduce.
  • Single-cell algae dies, clumps together and is removed by filtration.
  • 15' Cord Length

Removes heavy algae blooms usually within 10 days and keeps water green-free.
