What size streams for a 425

[VegasMike]

I may have asked you this before, but I could not find the thread.

I am in the planning stages of a 96"x36"x30" mostly SPS tank. I am going to put around 3000 gph through the return pumps and around 3000 gph through a closed loop mostly behind the rocks. I want to use the Tunze units for the rest of the flow.

I can't decide between two 6100's or four 6100's using the multicontroller.

What are your thoughts?

Start with 2 and add 2 more if necessary but I think I would try 2 first as this might do it with how much return flow and the closed loop you have planned.
