I am building my first ATS on a 180 saltwater setup and am hoping to get some design feedback from more experienced users. The tank will be heavily stocked with 20+ fish and mixed soft corals. Option 1 10" drilled pipe (fed by 3/4 full siphon tee'd to flow 300 gph) 10x10 screen 200 sq in total, roughly 8 cubes per day Both sides lit by a 45w CFL in round reflector or 36w LED grow light https://www.amazon.com/TaoTronics-L...1507655652&sr=8-1&keywords=taotronics+36w+led Cons: bottom 1" screen will be below water line (black line on the tank) Option 2 20" drilled pipe (fed by 3/4 full siphon, full flow from eheim 1262 return running about 600 gph) 20x6 screen 240 sq in total, 10 cubes per day Both sides lit by 2 ~23w CFL in round reflectors, 4 total 1 for each 10x6 area. I am not sure which design to go forward with, any insight or advice is appreciated! Here a shot of the full sump area for reference, the 40B will be plumbed into the acrylic sump, i have reserved the area in the acrylic sump to add a skimmer if needed.
