Wondering if a mag 12 (1200gph) would be enough for my tank?

Also still considering black sand or a mix of black and white

From the look of the overflow, I am guessing you are doing a herbie right? If so, for a 75 gallon (mine is 70 gallon from Concept too but not that big of an overflow box), you would be expecting the herbie to run at around 400gph through the pipe (although this is an highly variable parameter). I use speedwave 690gph as my return; cranked up to full so probably throwing around 400 or less at the return in the tank. Some people want high flow through the sump, some don't. But I would say, since its a mag and cannot be controlled, 1200gph might be a bit overkill. Go for a DC pump. Easy on the electricity, less noise, controllable and costs same as other pumps.
