Your flow is good if its 300 GPH at the height of the feed pipe. Your lights should be about 48 per side. They make larger CFL bulbs I just got a 44W and think they had a 50 something to.

At least. And if you want to run them for only 9 hours, you can double that.

However you need big deep wide reflectors, or else you'll burn the middle.
