Power Consumption Of A Reeflo Dart vs 1 WP40+2 Hydor Powerheads

[input80]

Here's a good question for the electricity gurus out there. My major concern is that the 120 I got came with a Reeflo Dart pump plumbed in for a closed loop. I have revamped it (lowered the plumbing dims from 2x1.5" bulkheads to 1 bulkhead into 2", then the ups are from 1.5 to 1" split into 3 Y loclines, which are .5"). My main concern is, would I be better off taking it out and keeping 2 hydor powerheads + 1 WP40 instead ? It looks like I can get more flow with the powerheads only, maybe the loclines are too small ?
Please let me know what you all think ? Although I don't pay the hydro bill, I just don't need the landlord knocking on my door.
