Pump advise

[Todd]

I am using one pump to run my skimmer and my return, through a manifold. I also added in an extra valve so that I could easily add on a chiller in the future. It does use extra space in the stand, but has the advantage of being tunable (ie, more flow to skimmer / chiller / return), adds less heat to the water (heat is transferred to the air, and not to the water as it would be with a submersible), and is quieter. I went for the quietest pump according to my research (Reeflo snapper) @ 2600 gph, it is quieter then my old skimmer pump (mag 12 @ 1200 gph). It also has less energy draw then two pumps, and could work out cheaper too (although you need to account for the cost of the additional plumbing)
