Bulkheads for 40 gallon breeder tank

[Borg]

First off I'd like to say hello and introduce my self. My names Roger from Ct and I've caught the fishtank fever just over two weeks ago. I literally woke up one day and had an impulse to get back into the aquarium hobby.

 

well actually it all started off with an old 45 gallon tank. Which I had turned it into a bait tank for shiners to be used for fishing.  1.5" overflow with a 1" return running off a sicce 3.0 submerged into my aqueon modular sump - model 3.

 

last week picked up a 40 gallon breeder and a 20 gallon long. Gonna build a nice stand this week for it.

 

heres my question....

which bulkheads should I use?  I'm planning on running a sicce 3.0 pump.  Could I use a 1" bulkhead for a center overflow with (2) 1/2" returns? On either side of the over flow.? Would love to hear any of your suggestions before I make my mind up and drill some holes. Thanks

I ran a 40g breeder and 20g sump with a mag 7 return pump using 2x 1" drains (herbie) and 2x 3/4" returns. 

 

I wouldn't do a single overflow due to the noise. 

 

Second tank (30g cube) I went with 2x 1" drains and a single 3/4" return.

Need to install plywood bottom. Then wrap three sides with 1/4" plywood. Tgen trim it out.

Tonight, im drilling holes, siliconing a overflow box. 

 

(2) 1/2" returns

(2) 1" bulkheads for overflow box.

 

think im going to setup a 20 long sump. Fluidized media.   

 

Anyone have any luck using a sicce syncra as an external pump?
