Cindy, the instructions say between the UV and the aquarium, putting a valve before the UV should be fine. Basically, I would have a tee after the filter output and a valve after each output of that tee. On the straight through frow of the tee I would have a straight tube going into another tee and teh straight trhough flow of that tee would go onto the hydor then to the aquarium. I would then plumb in the UV between the two 90 degrees off of the tees. When you need the UV simply close the straight flow valve and open the one for the UV, then turn on the UV. After a few days when you no longer need the UV, reverse those directions.
The reactor I would place inline after the Hydor although at this pont I woudl ditch the reactor and go with an in tank ceramic diffuser.
All that being said, I am not sure how much that will reduce the output of the filter. Personally I would not hook up the UV but instead run it as a HOB unit when necessary. Then all you have inline is the heator and reactor, much simpler and all the tees and valves will greatly reduce the output of the filter.
