First large mixed reef, suggestions fer a beginer

[lildingy]

Wanted to thank everyone for your support and help so far, and i am sorry fer piling all the questions on ya but here are a couple more

I am gonna drill the tank yeah

So as for the blukheads,
I am gonna run one a little lower and one bout an inch above it to the side, the lower will have a down turned elbow and a gate valve to "tune" it. The other will have an up turned elbow with a bunch of notches cut in it with the table saw as an emergency. What size do you think i should go with as far as bulk heads? Will 1" be too small? i really want to limit the size so i can limit it size of the overflow box. Also if this is not the best design or have anysuggestions please speak up, I am hoping this will be a quiet design.

For return i was gonna use 2x CA 2200 i think they are rated for 850gph with no head, but it is what i have on hand atm, most likely upgrade to a single external pump at a later date.
