you're right that there aren't a lot of pictures floating around for a Turbo-Twist UV
unit all set up. The closest thing I ran across was http://www.cloudytanks.com/reviews/aquariums/uv.html
The basic idea is to hang the Turbo-Twist on the back of your tank, remove the return hose from your canister filter which normally went back to your tank directly and connect it to the Turbo-Twist hose fitting nearest the 'on' light, and then to run a new hose from the Turbo-Twist hose fitting nearest the AC
adapter back into your tank where the canister filter return hose used to go. If the length of your existing canister filter return hose works out right, you can probably simply cut the existing hose and connect the Turbo-Twist in the middle !
