18W Non-Submersible UV Ultraviolet 14″ Light Clarifier Lamp Filter for Aquarium Koi Pond Fish Tank

The media could not be loaded.My dilemma was my old system uses 3/4″ piping and this UV light uses 1″ piping. To use the old pump with your new UV light you will need a) 2 x 1″ to 3/4″ coupler, b) 3/4″ to 1/2″ coupler (optional),1 foot of 1′ tubing (sold by the foot), and electrical tape. 1) cut 2″ from the 1″ tubing, wrap the tubing with electrical tape to protect from sun light, and connect to the input side of the UV light, then conecy to the coupler 1″ side, next connect the pump to the 3/4″ side of the coupler. 2) Wrap the remaining 1″ tubing with electrical tape and connect to the output side of light. Connect the coupler on the 1″ side. GET 2″ of 3/4″ piping and put the 3/4″ to 1/2″ on. You should now get a good flow out of the system. My app does not work with the camera and I have better thing to do with my time to spend 4 hour correcting it otherwise I would post pics. [...]
