I haven't worked out the exact specs of the lighting and flow yet. The predator tank doesn't require more than say 3 400W MH's however the Reef will need a nice sized bank of them to keep that lit to the right depth. The outlet in the 2000 will be a 4" 90 cupped upwards at the top of the tank, the inlet is a 2.5" so I just have to find a pump that will circ that effciently. I'm thinking the 1000 will have the entire back of the tank as the overflow allowing me to install all the 2" drains that I need. I'm not worried about sound because of the seperate room structure, so I could sound like niagra in there
