Gonna throw this out there for input, When it come to physics of water flow, Im a little rusty. debating with plumbing 1/2 vs 3/4 pipe. two pumps 1270
gph to 4 returns on top at each end, 2nd pump 790
gph in a closed loop from bottom of tank to 4 returns at each end of tank in bottom. This smaller pump will loop thru chiller. pre-filter will be in center of tank. Idea is to circle the tank flow with outputs on top and bottom. Dont want any circulators or powerheads in tank. Want nice clean look, for the fact its see thru tank. Also anyone out there have LEDs running on an odd shape tank other then a rectangle, like flat hex? concerned with coverage from single light unit, front to back of a 30inch wide by 24 inch deep tank. long side 80 inch and front hex is 48 inch. Appreciate everyones ideas and suggestions
