big pump, little pump ?

What's the GPH of the Dart if you put it in basement and have it push all that head? Your wanting SPS in your tank, right? So using the barracuda as the CL would be fine/. I'm running a Dolphin Amp Master 3000 GPH on my OM-4 in the 150. SO the Barracuda on a 180 shouldnt be bad. Hopefully not need any powerheads, thats for sure. For sump flow, I know slower, the more it acts as a refugeum, and will filter better, and have less microbubbles. I have a Little Giant for my 60g Sump return, About 1000GPH, will most likely have to throttle it back somewhat.
