What can I use to prefilter the water and how can I rig it up? Ideally,
I'd like it down to 5 microns to save wear and tear on the UV.

You will also need a valve to slow down the output of your
pump.....your UV filter will come with a gph rating that you must not
exceed. If you do, you will not be sterilizing your water as your
dwell time in the unit will be too short for the wantage of the bulb.
