This 36 Watt UV Clarifier is specially designed for retrofitting inside the EasyPro PS1FB and PSA5000 skimmers. The 36 Watt bulb is enclosed within a divider that replaces the PVC divider in either skimmer. Unlike many brands, the quartz sleeve does not include any gaskets.
Must be used with filter brush racks, not the filter pad style skimmers
Reduces maximum flow rate to 3600gph to allow adequate exposure time
