Run system off of one pump

[mr_alberta]

Hey all,

I'm slowly upgrading my 29 to the 37 and I'm gathering the pieces....

Anyway, I was wondering if it is a good idea to just use 1 pump on your system. I would use a beefier pump (i.e. Mag 9.5 or T3 through a SCWD or SS) or course. Is this a good idea? Do you think I would get some dead spots?

From sump to tank would be ~4 1/2' of head.
