The problem I see is with the flow rate. A UV filter needs a slow rate to be effective. If you split the return line with a valve on the UV side you could it. Of course this depends on the recommend flow rate for the UV and what your canister puts out.

yes you can i have one on mine if you want to slow down the flow just close the valve a bit till you get the flow that your looking for...are you going to use bio wheels with it ?
Are UV Lights even effective? If so Im looking at Coralife & off brands, does it make a difference? Do you mean using Bio-Balls in my Magnum? No because I have enough Live Rock already.
