I just purchased a coralife turbo twist UV sterilizer. I want to feed the UV with water coming from my cannister filter (Fluval 405). The Cannister is rated at approximately 300 gph and currently runs from the floor 4' up to the back of the tank. I now expect to run it to the UV and then to the tank. I want to find the best way to connect the two. Should I hook the UV onto the back of the tank, run the tube from the cannister 4' up to it and then run the output from the UV into the tank - about 6 to 8", or should I install the UV onto the back of the sump (ground level) and run a tube from the cannister to the UV (about 6") and then run a tube from the UV up 4' and back into the tank? My guess is that the best solution is the first which is to install the UV onto the back of the tank and run the tube from the cannister 4' up to meet it.
