Sump Design Input please!

I have a 30 gallon tank... I think I want to put the return in the middle and stuff the fuge off on the end. I want to have the compartment with the drain and filter sock cut out, which somewhat sucks because it takes up a lot of room... but I can stuff some of the skimmer under it so it's not all wasted.
The drain PVC device I made is on the left (the hole anyway), the filter sock hole on the right.

I ended up getting a little lazy so I quit adding baffles. I was thinking of doing an over > under baffle system instead of the over > under > over set up that is common. This is primarily to save me 2" overall. Additionally, I was thinking of adding a strip of foam across the top to help prevent micro bubbles from getting into the return side.



I wish it were possible to set the drain chamber along the side, but 4" filter socks prevent that with a 12" wide tank :\ . Anyway, please shoot me some input and perhaps some alternative designs that might make better use of my space. I could possibly throw the return and skimmer section together to really save some space, but I worry about micro bubbles with that set up. Though I could possibly route the outgoing skimmer water into an overflow baffle and thus prevent a lot of them that way.

 

What you have right there will work well. You dont really need a bubble trap on the right side. It looks like that will be the fuge side. You want the water to travel slowly through that side. Also remember to be careful how big the center is. If it is too small your return pump could suck it dry. It needs to be large enough to support the return load.

I have two drain pipes going into the back corners. The one dropping in to the fuge has a valve to slow the water down. The skimmer side is full blast, it works well.

 

I just noticed your drop in support piece. (my internet is slow loading pics) Are you putting that under your tank in a stand? If so, is there a way you can run PVC pipe down from the DT and mount it to the back of the stand below and let the PVC pipe hang into the back corners of the sump without an adapter? You would be able to move your skimmer close to the front and have room in the back corner for your socks.

How will you get the water over to the fuge side?

 

I will split the drain water from the display to feed the fuge and skimmer section. I need to have the PVC piece mounted into the corner piece because otherwise it wouldn't be quiet or allow the filtering. I can remove the bubble trap from the fuge side, I was worried about possible bubbles from the drain water entering that compartment, but I suppose there may be things I can do to remedy that.
