UV OPTION FOR PS1FB SKIMMERS
The PS1FB skimmer can be outfitted with a UV Clarifier!  The 36 watt bulb is enclosed inside of a divider that slips in the place of the PVC divider that is located behind the filter rack.  The UV option must be used with filter brush racks NOT the filter pad style skimmers.  The UV option will drop the maximum GPM flow from 100 to approximately 60 GPM to provide adequate exposure time. 

(Instructions: Skimmer UV)

Replacement UV bulbs and sleeves are available when needed.  All other parts last for years and years!
