The UNO, DUO, TRIO FILTER SYSTEM is a compact filter for ponds and water gardens, easy to install and designed for
easy maintenance. Besides offering 2 different fountain spray patterns, it performs three different filtering functions:
1. Multi Layer MECHANICAL Filtration to remove solids.
2. BIOLOGICAL Filtration to promote beneficial bacteria growth.
3. QUIET ONE PUMP for optimal performance and compact setup: Quiet One -2200 for UNO (594 GPH), Quiet One -
3000 for DUO (758 GPH) and Quiet One -4000 for TRIO (1022 GPH)
4. (OPTIONAL) ULTRAVIOLET STERILIZATION puts out 13 Watts of intense UV light to kill free floating algae. The
ultraviolet sterilizer has a separate plug so that you can operate it only when needed.
