One pump or two?

[pbauec]

I am on the fence but will need to pull the trigger and make a decision soon. I will have an above DT fuge (8' head) and my DT (5' head). I won't need too much flow in the fuge.
What are opinions on return pump(s)? Should i run two pumps or Tee off one larger pump ? My main concerns are power usage and quiet running but im sure i didn't think of everything.

Well for what it's worth, I have a fairly hefty blue line pump that's feeding my fuge, the DT and a manifold with UVS and reactors...

The fuge is about 3' of head with the DT 10-15' on the next floor.

I'm now looking for a second pump to run the fuge and manifold.

So yes, I would use two pumps.

I am leaning towards two pumps but didn't want to over equip and over power.

two pumps, so if one breakes you still got the recirculation
