opinions wanted regarding overflow for 150 gallon

[chwkreefer]

I have purchased a new 150 gallon (60"x24"x24") tank that will be put in between two walls and will be viewed from both 60" sides.

I would like some opinions on what overflow setup I should use. Right off the bat, I will mention I will be putting in just one overflow and the overflow will be at one end of the tank, either through the bottom or the side. (That much I am sure about)

Regarding a return pump, I will be using a mag 18 (which I already own) so I will be circulating approx 1300 GPH.

Should I drill the bottom and put in a durso? and box it in on one end of the tank?

Or possibly just drill a hole in the end of the tank and place a strainer on a bulkhead? What would the noise be like? Also, I know the flow capacity isn't as good.

I was leaning towards a durso boxed in and would then either make some agrocrete mould to fit around the overflow box or cut some live rock and use polyurethane foam to attach them around the overflow box (sort of like working with cultured stone).

I saw the use of polyurethane foam for attaching live rock in the book REEF SECRETS by Fossa and Nilsen. I will have to do some research on how long it takes for polyurethane foam to become inert.

Also, depending on which way I go, what size bulkhead?

TIA
