A properly run UV should be plumbed inline with your return pump so that the water is treated in its entirety to be as effective as possible, but a 36w UV wouldn't be nearly intense enough to have 1000-1100 gph run through it and still provide protection from Ich. This is the trouble with UV...it would add too much heat to your tank to use a properly-sized UV plumbed properly into the tank. Kind of lose, lose on this one.
