| As can be seen from the photos, my filter system are covered by wooden panels. What I did was just raised the wood that is about in the middle of the vortex, and place the UV there, attaching it to the wood. It is about 5 to 10 cm above water level. The painted white box is the housing. Since the UV is situated above the pipe out to next chamber, I believe almost 100% of the water is 'screen' by theUV light. Hence it is very effective. |
