Made by 2x cw-55, total up power: 110-watt. Package includes: 2x cw-55 with combine adapter, 2x hose fitting(3/4" to 1-1/2"), 2x 1-1/2" pvc fitting, 2x 2" pvc fitting. Jebao ultraviolet clarifier is not submersible and should be positioned outside the pond where there is little likelihood of it sitting in puddles or falling into the pond. It is recommended (but not necessary) that the up clarifier is attached to the tubing that enters the external pond filter. This prevents the flow restriction caused by the up restricting the flow of the filter.
