Good design for a DIY sump?

This is a picture of my sump. I'm just a beginning aquarist. The small section is for the refugium and the large section is for the skimmer and the return. Is this a good design? If not how should i change it to make it more efficient?

The skimmer is a reef octopus Ext-Ps-150 recirculating skimmer. How is it set up in sump.

 

Ok, i'm assuming there will be some small flow into the right side "refugium" and the main part on the left will have 5 inches or so of water to house the skimmer and return pump?

 

I personaly like the refugium to be bigger than the sump. Heres my set up... Luna

 

You will want your skimmer's water level stable, so put in another baffle to separate the return section, then the only flux will be in the return section. Also how will the water get from the fuge to the return section? the baffle is too tall, it should be lower to allow overflow into the return section.

 

what should i use to get a glass baffle out without damaging the rest of the sump made from a glass aquarium?

I have to reduce the footprint of my skimmer, what can I use to cut plexiglass?

 

Use a razor blade, be careful in the bottom corners, don't damage that silicone. You can use a table saw to cut plexiglass.
