overflow design

[Myreef55]

Hi all I just picked up a new 40 breeder to use as a frag tank in my basement fish room. I am trying to decide where to place holes and how many. Also to use an overfliw box or not. I was originalky thinging two one inch drains with upturn elbows on left and right corner and one 3/4" return in middle with locking split into two 3/4" returns in center of the tank. Do the upturned elbows work or should I buy an overflow box? Rather save the money if not necessary. If anyone has a picture of their drains and silencing devices and explain how they work I would appreciate any suggestions.

I used bean system  http://www.beananimal.com/projects/silent-and-fail-safe-aquarium-overflow-system.aspx I love it silents fail safe and easy to use plus small footprint

Yeah I guess I should change my question. Does anyone else use just bulk head and standpipes or strainers? Do you get adequate skimming of the top with the elbows? How do you keep them silent? I would rather not pay for the materials and use the space for box if the elbows will do the same thing. I know the more surface area the better but this is going to be a frag tank and like simplicity of no box.

I just have strainers. I point a one of the powerheads toward the surface, just enough to get a little action on top. Works great. I have 2 drains on the 180 and a reflow dart pushing the water com the sump. No problems as of yet.

I have a setup similar to what you are talking about.  Premium autos sells a great strainer for this setup.  I will see if I can get a video of my tank on here along with the strainer link

Here's a link to the strainer I use.  I am seeing up s small Frag tank and going with the same design only a single overflow.   The strainers keep it relatively quite unless you are right on top of them.

I have a video uploading now and will post when it is done.

I have 2 upturned drains.  3/4" running full syphon, and 1" Backup Drain. 

But I also isolated them with a top to bottom box, to limit how much water drains back when the power goes out.....and to help with surface skimming.  Cant see the upturns here, but you can see the box.
