Just wondering what are the risks, if any, of running my 18w Pentair UV from my return manifold (will have one...MAYBE two...reactors on it), back to the return line. This will be for a Red Sea Reefer 250, using the V3 sump. I'll probably go with a Vectra L2 return pump to supply the entire manifold/return. I'll go with a gate valve to each manifold split...and add a flow sensor between the gate valve and the UV to make sure I'm getting the proper flow through my UV.
The question is...what are the risks (if any) in tying the exit from the UV, back into the return line instead of dumping it back into the sump?
