Well, I think I am going to be doing abit of both.
I am going to switch all the return plumbing to flexible 3/4" tubing, put a T off the pump and a flowmeter, then have 2 returns to the tank, one from the main pump T and the other from the exit tube of the UV
Sterilizer. My biggest challeng is hiding the tubing from the UV
going back to the tabk, is it is a room divider and open on all 4 sides.
